Why You Feel Worse After Setting Boundaries

You’ve said no.

You’ve been clearer about what you need.

You’ve done the thing everyone says is “healthy.”

So why do you feel… worse?

Sometimes there’s relief, but often guilt can then follow, guilt for feeling like you’ve let someone down, then comes the overthinking, worrying about what the other person might now be thinking, and it leaves you sitting with a huge amount of anxiety.

If this sounds familiar, it doesn’t mean you’ve set your boundary incorrectly; this reaction often means you’re doing something very new.

Boundaries Don’t Just Change Your Behaviour, They Challenge Old Patterns

For many people, especially those who are neurodivergent or living with chronic health conditions, boundaries can feel particularly complex.

You may have spent years:

• Masking to fit in

• Prioritising others’ needs to avoid conflict

• Pushing through discomfort to meet expectations

• People pleasing and then feeling frustrated or resentful

• Being seen as “easy going,” “reliable,” or “low maintenance”

So when you begin to set boundaries, you’re not just changing what you do, you’re disrupting something your nervous system has learned feels much safer.

Even if those patterns were exhausting, they were familiar.

And familiar often feels safe.

Why It Can Feel So Uncomfortable

Guilt doesn’t mean you’ve done something wrong

Guilt often shows up when you go against old patterns, thoughts come up like:

“Don’t inconvenience people”, “Keep the peace, "Be easy to deal with".

When you set a boundary, you may feel like you’ve broken those rules, even if your boundary is completely reasonable.

That guilt is learned, the good news is, it can be recognised and changed.

Your Nervous System Is Adjusting

If you’re used to people-pleasing or masking, your body may interpret boundary-setting as a risk.

This can look like:

• A spike in anxiety after saying no

• Overthinking what you said and how they may feel about it

• Urges to go back and “fix” it

• Feeling physically unsettled or on edge

This isn’t because the boundary was wrong; it’s because it’s unfamiliar.

Other People Might Respond Differently

Sometimes, people benefit from you not having boundaries.

So when you begin to set them, you might notice:

• Pushback

• Disappointment

• Subtle guilt-tripping

• Changes in how someone relates to you

This can reinforce the feeling that you’ve done something wrong; this is where anxiety can come up, and it can feel safer to ‘go back and fix it’

You’re Building A New Relationship With Yourself

Boundaries are not just about other people; they’re about self-trust.

If you’re not used to listening to your own needs, that can feel uncertain at first.

You might find yourself asking if you're being too much, if this is reasonable, or even if I should just let it go

When ADHD, Autism, or Chronic Illness Are Part of The Picture

Boundaries can feel even more layered when your capacity fluctuates, or your needs aren’t always visible to others.

You might be navigating:

• Energy that changes day to day

• Sensory overwhelm

• Executive functioning challenges

• The pressure to appear “fine” or consistent

This can lead to:

• Overcommitting on a “good” day

• Cancelling when things shift

• Feeling unreliable or guilty

• Pushing through at the expense of your well-being

Setting boundaries in this context isn’t just helpful, it’s essential.

But that definitely doesn’t make it any easier.

The Important Difference: Hard vs Wrong

There’s a difference between something feeling hard and something being wrong.

Boundaries are often hard because:

They go against old patterns and conditioning, they change relationship dynamics, and they require you to tolerate discomfort.

But none of that means they’re wrong.

What Can Help in the Moment

When that wave of guilt or anxiety hits, it can help to gently remind yourself:

“This feels uncomfortable because it’s new, not because it’s wrong”

“I’m allowed to have limits, even if others don’t like them”

 “I don’t need to fix this feeling immediately”

You don’t have to override the discomfort; acknowledging it and learning to sit alongside it is part of the process.

A Gentle Reflection to Consider

You might want to ask yourself:

• What would it cost me if I didn't have this boundary?

• What am I trying to protect or care for by setting it now?

• If someone I cared about set this same boundary, would I think they were wrong?

You’re Allowed to Do Things Differently

If setting boundaries leaves you feeling unsettled, it doesn’t mean you’ve failed or done something wrong; it often means you’re stepping out of patterns that often kept things predictable in the past, even if they felt draining or left you with frustration or resentment.

Over time, with practice and support, boundaries can begin to feel less like something you have to force and more like something that comes naturally.
