why everything feels harder when you're overwhelmed: adhd, executive functioning and capacity
Updated: 5 days ago
There's a particular kind of frustration that comes from knowing exactly what you need to do, and still not being able to do it.
You know you need to reply to that email.
You know the assignment is due.
You know the washing needs doing.
You know you should book that appointment.
You might even have a really good plan for getting it all done. And yet here you are on the couch, scrolling, reorganising your notes for the third time, or just staring at the task like it's personally offended you.
Then the inner commentary kicks in:
Why am I like this?I'm so lazy. Everyone else seems to manage. I just need more discipline.
If that's you, you're not alone, and you're not broken. For many people, especially those with ADHD or other differences in executive functioning, this "knowing-doing gap" is a very familiar part of daily life.
It's also worth saying that not every experience of overwhelm is ADHD. Stress, exhaustion, anxiety, low mood, big life changes and too many competing demands can all make it harder to concentrate and get started.
So instead of asking "what's wrong with me?", a more helpful question is often:
"What's making this hard?"
knowing what to do isn't the same as being able to do it
We tend to talk about tasks as if they only need knowledge. But you already know how to send an email. Knowing how was never the problem.
Real-life tasks ask a lot more of us. To get one done, your brain has to remember what you're doing, decide where to start, guess how long it'll take, ignore distractions, switch gears, put up with a bit of discomfort and keep going long enough to finish.
Those behind-the-scenes skills are often grouped under the term executive functioning. Research has found meaningful executive-function differences in adults with ADHD, but it also shows that executive functioning doesn't explain everything about ADHD or everyday life.
The takeaway is that "you know how to do it, so you should be able to do it" is a much too simple idea. People are more complicated than that (thankfully).
why overwhelm makes ordinary tasks feel enormous
Think of your capacity as the mental and emotional room you have available right now.
The task doesn't change. Your room does.
Take one email. On a settled day, you open the laptop, write it and move on. On a day when you're tired, stressed, distracted and already juggling twelve other things, that same email turns into:
What should I say? How do I word it? Do I need to explain? What if they misunderstand? Should I send it now? Should I check it again? What else have I forgotten?
Suddenly it's not an email. It's a stack of decisions. This is why reducing friction often works better than trying to summon more motivation.
stress affects thinking, not just feelings
Stress isn't only an emotional experience. Research suggests that acute stress can affect things like working memory and mental flexibility, although the picture is nuanced and varies from person to person.
That doesn't mean your brain has "shut down" or that you can't function. It just means that when you're under a lot of pressure, some of the mental resources you normally rely on can be harder to reach.
Sometimes the most helpful first step isn't another productivity system. It's lightening the load.
capacity vs. character
One of the most painful habits is turning a capacity problem into a character problem.
Capacity: "I've had a huge week, and I'm struggling to get started."
Character: "I'm lazy."
Capacity: "I'm taking on too much and need to rethink what's sustainable."
Character: "I'm terrible at coping."
Capacity: "Transitions are hard for me, and I need more structure."
Character: "I should be better at basic life."
The character version feels like an explanation, but it doesn't tell you what to change. It just tells you to feel worse.
try a friction audit
Next time you're stuck, skip "how do I make myself do this?" and ask: What exactly is getting in the way?
Is the task...
Too vague? Turn it into a visible first step.
Too big? Shrink it to the smallest useful version.
Too boring? Add some stimulation, like music, a body double or a friend on the phone.
Too emotionally loaded? Notice what it stirs up before you try to push through.
Too decision-heavy? Pre-decide the next step.
Too easy to forget? Get it out of your head and into a reminder.
Competing with everything else? Reduce how much you're trying to hold at once.
Hard to switch into? Create a cue or little ritual to get you started.
This isn't about finding the one perfect ADHD hack. It's about understanding the problem more specifically, so you can respond to it more kindly.
build the minimum viable version
Here's one of the most useful questions for an overwhelmed brain: What's the smallest version of this that still counts?
"Clean the house" becomes clear the kitchen bench.
"Get on top of uni" becomes open the document and write the heading.
"Exercise four times this week" becomes go outside for ten minutes.
The minimum version isn't the finish line. It's the front door. And once the door is open, you learn a lot about what actually helps you start.
build routines for your real days, not your best days
We've all designed a routine for a fictional person. She wakes up early, exercises, meal-preps, replies to emails instantly, keeps a tidy house and has flawless boundaries. She never gets overwhelmed.
Then real life turns up. You sleep badly, work gets busy, someone needs you, you get sick, or your feelings take up more room than usual. The routine collapses, and it feels like you failed.
A more sustainable option is to build in different levels:
High-capacity day: cook dinner, exercise, tackle admin.
Average day: simple meal, short walk, essential admin only.
Low-capacity day: easy food, basics, one essential task, rest.
That's not lowering the bar on your whole life. It's recognising that human capacity changes, because you're a human.
and what about self-compassion?
Self-compassion often gets mistaken for "being nice to yourself" or letting yourself off the hook. A more useful way to see it is responding to difficulty with less unnecessary hostility and more curiosity about what's actually going on.
Research links self-compassion with lower levels of psychological distress, and a large 2025 systematic review pointed to things like repetitive negative thinking and avoidance as possible reasons why. That said, we're still learning which approaches help which people, and it's not a cure-all.
The practical question is simple:
Does the way I talk to myself help me understand and respond to this, or does it make it bigger?
understanding yourself isn't giving up
Some people worry that accepting their limits means lowering their expectations forever. It doesn't have to.
Understanding yourself usually makes change more specific:
Instead of "I need more discipline," you might find "I need fewer decisions in the morning."
Instead of "I need to stop procrastinating," you might find "I struggle to start when the first step is unclear."
Instead of "I need to stop being so sensitive," you might find "certain environments overload me, and I need different boundaries."
Instead of "I need to cope better," you might find "my current life asks more of me than I can sustainably give."
Those are very different problems, and different problems need different solutions.
you don't have to fight yourself harder
After years of struggling, many people end up in a constant inner tug-of-war: Come on. Just do it. You're better than this. Why can't you just be normal?
That battle is exhausting all by itself.
There's another way. Get curious about the pattern. Notice what feeds it. Get clear on what you need. Then start from there.
Depending on you, that might mean practical strategies for executive functioning. It might mean looking at self-criticism, anxiety or perfectionism. It might mean exploring relationships, boundaries or people-pleasing, or making sense of past experiences. Sometimes it means having someone alongside you while you work it out.
The goal isn't a life where you never struggle. It's a life that feels more sustainable, more connected and more genuinely yours.
when it might be time to talk to someone
It may be worth speaking with a psychologist if these patterns are persistent, distressing, getting in the way of work, study, relationships or daily life, or if you've been trying to manage them on your own and feel stuck.
