Why Can’t I Handle Stress Like I Used To?

There was a time when you could handle far more than this.

A major deadline. A difficult conversation. A problem at work that needed sorting immediately. You dealt with it.

Yet now, an unexpected email can throw you. Someone asks one more question at the end of a long day and you can feel yourself becoming irritated, tearful or completely overwhelmed.

And perhaps the most unsettling part is the thought underneath it:

What has happened to me? I used to cope with so much more than this.

If stress feels harder to handle than it used to, it does not automatically mean you have become less resilient or less capable. Often, your available capacity has been gradually reduced by sustained demand, too little meaningful recovery, mental load and years of pushing through.

When you are already carrying a high baseline of pressure, a smaller stressor can take you beyond the margin you once had.

The problem may not be that you suddenly cannot cope: It may be that you have been coping for too long.

Why smaller stresses can feel harder now

Your capacity is the mental, emotional and physical room you have available to respond to what life asks of you.

It is not fixed.

Imagine the same small disruption landing on two different days.

On one, you have slept well, work has been manageable and you have had some space to think. On another, it arrives after months of deadlines, interrupted sleep, family responsibility and constant decision-making.

The disruption has not become more serious. It is simply landing in a very different context.

There is less room around it.

That is often what women mean when they say:

I don’t understand why this is affecting me so much.

The thing in front of you may be relatively small.

The load underneath it isn’t.

How prolonged pressure reduces your spare capacity

One of the images I love for understanding this is a raincoat.

When the waterproofing is good, rain lands and beads away. You barely notice it.

But after repeated wear, that protection becomes less effective. Eventually, water that once rolled straight off starts getting through.

The weather does not necessarily have to be worse.

What has changed is the protection available to meet it.

Our capacity can feel a little like that.

Human beings can manage periods of intense demand remarkably well. The problem is when one difficult week becomes another without enough genuine recovery between them.

You keep functioning. You adapt. You find another gear.

But the margin gradually becomes smaller.

Eventually, something that once would barely have registered feels like far too much.

I explored this idea of tiredness, stress resilience and changing capacity in episode 22 of the Thrive Bright Podcast, Why You Feel Tired.

The small thing is often not the whole problem

This is why the final straw can seem ridiculous.

The dishwasher has not been emptied. Someone asks what is for dinner. The Wi-Fi stops working.

A colleague sends a slightly abrupt email. Your child cannot find the thing you reminded them three times to pack.

And suddenly you are furious, crying, shutting down or thinking:

I cannot deal with one more thing.

Then the self-judgement arrives.

Really? This is what has tipped me over?

But the dishwasher is rarely just the dishwasher. It is the dishwasher on top of the deadline. On top of remembering the appointment.

On top of waking at 3am thinking about something you forgot to do. On top of being the person everyone comes to when there is a problem. On top of months of telling yourself: Just get through this week.

Your response makes much more sense when you look at the whole load rather than judging yourself by the final thing that happened.

Why high-achieving women can notice reduced capacity late

For a high-achieving woman, being able to cope may have become part of how you understand yourself.

You are capable. Reliable. The one who works things out.

The one people trust.

Perhaps you have spent years being told:

I don’t know how you do it all.

And for a long time, you did.

So when ordinary things begin to feel harder, you may not naturally think:

I wonder whether I am carrying more than my current capacity can sustainably hold.

You are much more likely to think:

Why can’t I handle this anymore?

I need to get myself together.

Other people manage.

I’ve been through much worse than this.

That last thought can be especially convincing. You may genuinely have navigated harder periods before and somehow kept moving. But previous evidence that you could push through does not mean you have an unlimited ability to keep doing so.

High-achieving women can also become skilled at compensating. When energy drops, you organise harder. When concentration is poorer, you work later. When there is too much to hold, you become even more responsible.

That can hide reduced capacity for a surprisingly long time.

High functioning does not mean fully resourced

Reduced capacity can be difficult to recognise because you may still be functioning extremely well.

You are still going to work, running the business, meeting deadlines, replying to messages and keeping home life moving.

From the outside, nothing looks dramatically wrong.

But functioning and being well-resourced are not the same thing.

You can continue producing an enormous amount while the effort required to produce it gets higher and higher.

Work that once felt straightforward takes more concentration. Decisions feel heavier. You have less patience by the evening and need longer to recover after a demanding day.

You may find yourself longing to be left alone, then feel guilty when you finally get the chance.

You are technically still coping.

But there is almost no spare capacity left.

This can be part of burnout in high-achieving women, particularly when prolonged pressure has been normalised for so long that depletion is only noticed once everyday life becomes harder to carry.

Why pushing harder can make reduced capacity worse

The difficult irony is that when capable women notice they are struggling, they often respond using the strategy that has served them throughout their lives.

They push harder. Become more organised. Try to be more disciplined.

Catch up at the weekend. Work later so tomorrow will feel easier.

Get annoyed with themselves for being less productive.

The assumption is:

I need to get back on top of everything.

But if the underlying problem is that demand has repeatedly exceeded your available resources, demanding even more from yourself does not rebuild those resources.

It adds another layer of demand.

The more depleted you feel, the harder you push to compensate.

The harder you push, the less opportunity there is for meaningful recovery.

The behaviours that previously helped you succeed can become part of what keeps you depleted.

What actually helps rebuild your capacity?

Rebuilding capacity is not necessarily the same as doing nothing.

And it is rarely solved by a single weekend off.

Different kinds of demand drain us in different ways.

You can spend an evening sitting on the sofa while still answering messages, scrolling, making decisions, thinking about tomorrow and mentally carrying everybody else.

Your body has stopped moving.

Your mind has not stopped working.

Sometimes the more useful question is not:

How do I make myself rest more?

It is:

What is actually draining me?

If the drain is constant decision-making, fewer decisions may matter. If it is emotional responsibility, you may need spaces where you are not the person holding everyone else. If it is relentless mental activity, genuine mental quiet may be more restorative than another evening spent consuming information.

This is why different types of rest can matter in burnout. The thing that restores you needs to have some relationship to the thing that has been draining you.

It can also help to look beyond obvious stressors. Some parts of life repeatedly take energy while others genuinely return something to you. I explore that distinction in From Drainers to Sustainers.

The aim is not a perfect recovery routine. It is understanding your pattern well enough to stop asking an under-resourced version of you to keep producing as though nothing has changed.

Rebuilding capacity can start smaller than you think

When women realise the way they are living is no longer sustainable, recovery can quickly become another project.

New routine. New boundaries. New exercise plan.

Fix the sleep. Change the workload. Sort everything.

Now.

And suddenly getting better becomes another thing you are trying to do perfectly.

But capacity is often rebuilt through smaller, repeated changes.

• One commitment that does not need to be yours.

• One evening that does not become an opportunity to catch up.

• One request you pause before automatically saying yes to.

• One expectation you realise nobody is holding except you.

• One moment when you respond to tiredness as information rather than an inconvenience.

You do not need to burn your life down.

But you may need to stop expecting the same depleted system to carry an ever-increasing load.

And if a significant change in how you are coping is sudden, persistent or accompanied by physical or emotional symptoms that concern you, it is worth speaking with an appropriate healthcare professional. Not every change in capacity is burnout, and stress does not explain everything.

A gentler way forward

If things affect you more than they used to, you have not necessarily become less capable.

Perhaps you have been capable for a very long time.

Perhaps you have spent years meeting the demand in front of you without noticing how little room remained behind it.

Perhaps this version of you does not need another lesson in how to push through.

She needs you to notice what she has been carrying.

You can be deeply capable and still have limits.

You can be ambitious and need recovery.

You can be the woman people rely upon and still need support yourself.

The question does not have to be:

How do I get back to being able to cope with everything?

A more useful question might be:

What would need to change so that my life no longer requires me to cope at the edge of my capacity?

Not by asking you to become better at coping.

By helping you create more room inside the life you are already living.
