Is It Anxiety Or ADHD? What Parents Of Neurodivergent Kids Need To Know about ADHD and anxiety in children

Is It Anxiety… Or Is Your Child's ADHD Brain Overwhelmed?

By Izabela Doyle | No More Meltdowns

Every week I speak to parents who are exhausted from doing everything right.

They validate feelings. They use calm voices. They've read the books, followed the accounts, tried the breathing exercises. And their child is still refusing school. Still melting down over homework. Still exploding when plans change.

And everyone keeps saying the same thing: "It's anxiety."

Maybe. But maybe not entirely.

Because here's what most parents — and honestly, many professionals — don't tell you.

Up to 50% of children with ADHD also have anxiety. Which means if your child has ADHD, there is a coin-flip chance that anxiety is genuinely part of the picture.

But here's the part that changes everything: even when anxiety is real, it is very often not the root. It is sitting on top of something else. And if we treat the anxiety without finding what's underneath it, we keep getting the same result. We manage the moment. The problem comes back.

I know this — not just as a neurodivergent family coach — but as a mum.

My Son and the Maths Day Tummy Aches

My son has school-based avoidance. He gets tummy aches before school. He doesn't want to go — especially on maths days. Sometimes he looks so unwell that school phones me to come and collect him early.

And I am a neurodivergent family coach. This is literally what I do for a living. And I still get those calls.

Here's what I know about my son. He worries about not finishing tasks in time. About zoning out in class and missing something important. About not passing tests.

Those worries are real. The tummy aches are real.

But underneath those worries? There are specific, unsolved problems. And the anxiety — the tummy aches, the early pickup calls, the maths day dread — is what happens when those problems keep not getting solved.

That distinction — between the anxiety and the root underneath it — is what I want to walk you through today.

Two Trees, Same Leaves

Imagine two trees. From the outside they look identical. Same shape, same branches, same leaves. But underground, they have completely different roots.

One tree is rooted in anxiety. The other is rooted in ADHD and executive function overload.

And the leaves — the things you are seeing every day — look the same on both trees.

Avoidance. Meltdowns. Refusal. Irritability. Sleep problems. Constant reassurance-seeking. Big emotional reactions that seem completely out of proportion to what just happened.

So we look at those leaves and say: this child is anxious.

But if we treat the leaf and miss the root, we get short-term relief. And the problem keeps coming back. Which is exactly what was happening with my son. We were responding to the anxiety — the tummy aches, the avoidance — without asking what was specifically hard about maths. And it came back. Every maths day. Like clockwork.

The question that changes everything is not "how do I stop this behaviour?" It is: what is making this situation hard for my child?

Because behaviour is not the problem. Behaviour is the signal.

What ADHD Is Really Doing

Most people think ADHD is about attention. It is so much more than that.

ADHD affects your child's brain management system — what researchers call executive function. Think of it as your child trying to run their day with too many tabs open at once.

Executive function covers starting tasks, stopping tasks, shifting from one thing to another, holding information in mind, managing time, regulating impulses, regulating emotions, planning ahead, and coping with frustration when things don't go as expected.

When that system is under pressure — and for an ADHD brain, everyday demands put it under pressure constantly — the child looks anxious. Not because they are choosing to be difficult. But because the demand in front of them is bigger than their current capacity to handle it.

I see this with my son on maths days. It is not that he is afraid of maths in the way we typically think of fear. It is that his brain can already feel — before he has even left the house — that the demand is going to exceed his capacity. The tummy ache is his body's way of saying: I can already feel this is going to overwhelm me.

That is executive function overload wearing the costume of anxiety.

So when your child says "I can't go" — that might not mean fear. It might mean: I don't have the capacity for this right now. And that needs a completely different response.

The Hidden Load You're Not Seeing

Think about what Monday morning actually asks of your child.

They have to wake up and shift out of sleep. Transition from home mode to school mode. Get dressed and manage any sensory discomfort. Remember everything they need. Move through a sequence of tasks without losing track. Face the unpredictability of what the day will hold. And enter a busy, noisy environment.

All before 8:30am.

That is not a small ask. That is a full executive function workout before the day has even started.

And homework is the same. When you say "it's only ten minutes" — your child's brain hears something very different. Remember what the teacher said. Find the right book. Understand the task. Start writing. Stay focused. Tolerate making mistakes. Keep going when it feels hard or boring.

That is not ten minutes. That is everything their brain finds hardest — all at once — at the end of a day when they are already depleted.

When they explode, it is not defiance. It is overload.

And this is the part most people miss: it is not a motivation problem. It is a capacity problem.

Why They Feed Each Other

Here is where it gets genuinely complicated, and I want to be honest with you about this because I think it is the part that trips most parents up.

ADHD and anxiety do not just look similar. They feed each other.

When your child is stressed, their brain shifts into protection mode. The thinking, planning, problem-solving parts go partly offline. Which means the executive function skills they already find hard become even harder under stress.

Overload creates stress. Stress makes thinking harder. Harder thinking creates more overwhelm. And round it goes.

So when you say "just calm down and think" — they genuinely may not be able to. The thinking part of the brain is not fully available.

When my son is already in that cycle — already dreading the maths lesson before he has left the house — telling him it will be fine does not touch it. Because his nervous system is already in protection mode. What he needs is not reassurance. What he needs is for the actual problem to get solved.

This is also why sticker charts and consequences so often fail these children. Those approaches assume the child already has the skills and just needs motivation. But as Dr Ross Greene, developer of the Collaborative and Proactive Solutions model, puts it: kids do well if they can. Not if they want to. If they can.

My son wants to go to school. He wants to not worry about maths. He wants to feel capable. Wanting is not the problem. Capacity is.

The Story That Shows You What's Possible

A mum I worked with — I'll call her Sarah — had been stuck in school morning meltdowns for nearly two years. Every single morning. Uniform battles, crying, shouting, sometimes total shutdown. By the time they got in the car, everyone was already exhausted.

She had tried everything. Earlier wake-up times, visual schedules, rewards, consequences, talking it through the night before. She was using anxiety strategies — calm voice, validation, breathing exercises. Same result, every Monday.

When we started working together, I asked her one question. Not "what does your daughter do?" — Sarah could describe that in exhausting detail. I asked: "What is actually hard about Monday mornings for her?"

And Sarah went quiet. Because she realised she didn't know. She knew the behaviour. She didn't know the problem.

When Sarah stayed curious and started asking her daughter — not in the middle of the meltdown, but calmly, at the weekend — her daughter eventually said: "I hate not knowing if Mrs Henderson is going to be there."

That was it. A teaching assistant. Warm, predictable, familiar. And sometimes absent on Mondays without warning.

That uncertainty was the problem. Not school. Not leaving the house. Not separation anxiety.

So Sarah contacted the school and asked one thing: "Can you let us know on Sunday evenings if Mrs Henderson won't be in?"

One text message. Monday mornings changed within two weeks.

Not because the behaviour was managed. Because the right problem was finally solved.

The Reframe That Changes How You See Everything for ADHD and anxiety in children

This is the shift that Collaborative and Proactive Solutions teaches us to make.

Instead of "my child refuses homework" — you say: "my child has difficulty starting written homework after school when they are tired and the instructions are not fully clear."

Instead of "my child is anxious about school" — you say: "my child has difficulty going into school on Monday mornings when they don't know what has changed over the weekend."

Instead of "my son dreads maths" — I say: "my son has difficulty tolerating the feeling that he might not finish the work or might zone out, and he does not yet have a strategy for what to do when that happens."

One version makes the child the problem. The other makes the problem the problem. And that is where you can actually start.

What To Actually Do

Step one: pick one moment.

Not "the anxiety." Not "school avoidance" as a broad category. One specific, recurring situation that keeps going wrong. Getting dressed on school mornings. Starting homework after dinner. Maths days. Whatever keeps producing the explosion or the shutdown — start there.

Step two: get curious at a calm time.

Not in the middle of the meltdown. Not in the car on the way to school. Find a quiet moment — after dinner, at the weekend — and open the conversation like this:

"I've noticed maths days have been really hard lately. I'm not upset about it — I just want to understand what's going on for you. What's the tricky part?"

Then stop talking. And really wait.

Step three: when they say "I don't know" — stay with it.

Most children will say "I don't know" the first time. That is not the conversation failing. That is your child never having been asked to name this before. So you gently help them find it.

"Is it the starting the work, or getting stuck in the middle?" "Is it worrying about finishing in time?" "Is it not knowing what to do when you zone out?"

You are not interrogating. You are helping them find words for something that lives in their body as a tummy ache.

Step four: share your concern, then solve it together.

"I get that maths feels really overwhelming. My concern is that leaving school early is making it feel even bigger over time. I wonder if there's something we could try — something that means you don't have to carry this alone."

Now both concerns are on the table. And you are working on the same problem instead of against each other.

This is not permissive parenting. This is not letting your child run the house. This is the most rigorous, respectful skill-building work you can do with a neurodivergent child. Because what they are practising in that conversation — flexible thinking, communicating their experience, working toward a solution — are exactly the executive function skills their brain finds hardest.

You are not just solving this week's problem. You are building skills they will need for the rest of their life.

What This Means for the Anxiety

My son's tummy aches did not get better because I taught him to manage his anxiety.

They got better when we found the specific things that were hard — the fear of not finishing in time, the dread of zoning out and missing instructions, not knowing what to do when that happens — and we started solving those things together.

The anxiety was real. But it was sitting on top of unsolved problems. And once we started solving those problems, his nervous system had less to be anxious about.

That is what is available for your child too. Not a child who copes better with a hard situation. A situation that actually fits your child better. That is the difference. And it is worth everything.

Ready To Find the Root?

If you have been managing the anxiety and the same problems keep coming back, it is not because you are not trying hard enough. It is because the root has not been found yet.
