If you have ADHD and you’ve ever been told you’re “too sensitive,” “overreacting,” or that you “take things too personally,” there’s a neurological reason this might be happening — and it’s not a character flaw.

A big part of the story lives in something called the Default Mode Network (DMN).

What Is the Default Mode Network?

The Default Mode Network is a set of brain regions that turn on when you’re not focused on the outside world. It’s active when you’re:

Daydreaming
Reflecting on the past
Imagining the future
Thinking about yourself
Replaying conversations
Wondering what others think of you

In short, the DMN is the brain’s “inner world” network.

It helps with:

Self-awareness
Emotional meaning-making
Memory + personal narrative
Empathy and social understanding

It’s the part of your brain that asks:

“What did that mean?”
“Why did they say that like that?”
“What does this say about me?”

ADHD Brains and the DMN: A Tricky Relationship

In people without ADHD, the brain shifts fairly smoothly between:

Task mode (focus, problem-solving, doing)
Default mode (internal thoughts, emotions, self-reflection)

But with ADHD, the DMN often:

Turns on too strongly
Turns on at the wrong times
Is harder to “turn down” when trying to focus

This means the “inner world” doesn’t just visit — it takes over the room.

So instead of:

“That comment was annoying.”

The ADHD brain goes:

“Why did they say that? Are they mad at me? Did I do something wrong? Do people secretly feel this way about me? Why does this always happen?”

Your emotional brain and self-referential thinking get more airtime than you asked for.

Why This Makes Feelings So Intense

Here’s where the depth of emotion comes in.

The DMN is deeply connected to areas of the brain involved in:

Emotional memory
Social pain
Self-evaluation
Rejection processing

So when something happens — especially socially — it doesn’t stay a surface-level experience.

It becomes:

1. Personal

The DMN constantly links experiences back to you.

“What does this mean about me?”

2. Meaning-heavy

Your brain doesn’t just feel the moment — it searches for significance.

“This isn’t just a bad interaction. This means something.”

3. Hard to let go

Because the DMN is active during rumination, the feeling doesn’t pass quickly. Your brain keeps replaying and reprocessing it.

That’s why:

Criticism can feel devastating
Conflict can feel catastrophic
Rejection can feel physically painful
Embarrassment can linger for years

It’s not drama. It’s neural amplification.

Emotional Depth Is the Other Side of the Same Coin

The same system that makes painful emotions intense also fuels:

Deep empathy
Strong attachment
Passion
Creativity
Big joy
Powerful intuition about people

Many people with ADHD:

Read rooms quickly
Sense emotional shifts instantly
Care deeply about fairness and connection

Your nervous system is tuned to emotional frequency at high volume.

The issue isn’t that you feel deeply.
The issue is that the “volume knob” is sensitive and hard to regulate.

The Missing Piece: Regulation, Not Toughness

People with ADHD are often told to:

“Have thicker skin”
“Don’t take things so personally”
“Just let it go”

But the real skill that helps isn’t emotional suppression — it’s nervous system regulation.

Because when the DMN is loud, the goal isn’t:
“Stop feeling”
It’s:
“Help the brain shift networks.”

Helpful tools often include:

Movement (walks, stretching, shaking out tension)
External focus (music, sensory input, hands-on tasks)
Mindfulness practices that anchor to the body
Naming the emotion without analyzing it
- “I’m feeling rejected” vs. “Why does this always happen to me?”

These help move the brain from:
Self-referential loop (DMN) → Present-moment engagement

You’re Not “Too Much.” Your Brain Processes Deeply.

ADHD isn’t just about attention. It’s about intensity:

Intense focus
Intense emotion
Intense thought loops

Your brain isn’t built for shallow processing — it’s built for depth.

The goal isn’t to become less emotional.
The goal is learning how to ride the waves without drowning in them.

And that starts with understanding this truth:

Your feelings aren’t a flaw.
They’re a feature of a brain that experiences life in high resolution.
