Why Does Anxiety Make Us Imagine the Worst?

Why does your mind automatically assume the worst… 

even when there’s very little evidence that something bad will happen?

Why does one unanswered text, one strange symptom, or one missed phone call… suddenly spiral into worst-case scenarios in your mind?

Why do you find comforting thoughts so much easier to question than scary ones?

And why is it that sometimes…

It’s not because you worry too much…

It’s because your brain is trying to look out for you?

THE STORY

She sent him a text.

Then he didn’t reply.

Five minutes passed.

Ten minutes passed.

Eventually, half an hour went by.

And her mind immediately started working overtime.

“Did I say something wrong?”

“Are they mad at me?”

“What if they don’t reply?”

The longer she waited… the scarier the thoughts became.

By the time he finally texted back… she had convinced herself he was annoyed with her… that they were fighting… and that he even might have accidentally injured himself.

His reply simply said:

“Sorry, in a meeting.”

She let out a sigh of relief.

But then she found herself wondering:

“Why does my mind jump to the worst possible conclusion?”

INSIDE THE MIND: WHAT’S HAPPENING UNDERNEATH

When you worry, your brain isn’t trying to scare you. It’s trying to keep you safe.

Your brain would much rather prepare you for a danger that doesn’t exist than fail to prepare you for the real thing.

The problem is: modern life provides a lot of potential dangers that don’t actually pose any real threat.

WHAT’S REALLY GOING ON

When you feel anxious, your brain may become increasingly focused on what could go wrong.

At its core, anxiety is about uncertainty.

Your brain hates unanswered questions.

It hates not knowing what’s going to happen next.

And it hates feeling out of control.

So when your mind is left wondering, “What if?”

It makes up scary scenarios to fill in the blanks.

YOUR BRAIN ON ANXIETY

Part of your brain’s job is to keep you safe.

And one of the ways it does that is by scanning your environment for threats.

“What could go wrong?”

“Where are the dangers?”

These aren’t questions your brain asks because something bad is happening.

They’re questions your brain asks to try and prevent bad things from happening. 

To your brain:  

Ignoring danger = bad.

Noticing potential danger = good.

THE SCIENCE OF WHY WE IMAGINE THE WORST

Your brain is designed to keep you out of danger.

Your amygdala — an almond-shaped part of the brain involved in detecting and responding to possible threats — helps you quickly detect danger in your environment.

But that’s not all…

Your brain also naturally gives more attention to negative or threatening information.

This is called the negativity bias.

For our ancestors, missing a real threat could have serious consequences.

Being overly alert to possible danger was often the safer response.

These days, most of the things we worry about aren’t life-or-death situations.

But our threat system can still respond as though everyday uncertainty deserves the same attention.

And because we’re hardwired to keep our focus on danger… we can still worry intensely about situations that are uncomfortable even when they are not truly dangerous.

REAL-LIFE SCARES

Scenarios that trigger your anxiety are usually a sign that your brain thinks danger may be present.

That’s why you overthink that text before your partner replies.

That’s why you assume that headache must be a brain tumor.

That’s why you stress about making one mistake at work.

That’s why you immediately think your child is in trouble when they don’t answer your call.

Danger = bad, right?

To someone else, your anxious thoughts might seem extreme.

To you, they might seem like catastrophes waiting to happen.

THE DIFFERENCE BETWEEN ANXIETY AND INTUITION

Anxiety can feel like intuition telling you that something is wrong.

But often, it is your brain warning you that something might go wrong.

There is a difference.

ASK YOURSELF THIS…

Instead of asking yourself why you always imagine the worst…

Ask yourself…

“What do I believe my brain thinks could go wrong?”

Learning what situations trigger your anxiety can help change your relationship with your anxious thoughts.

WHAT YOU CAN DO

When your mind jumps to the worst conclusion…

Pause.

Take a deep breath.

And ask yourself…

“What evidence do I have that this will happen?”

“What else could be going on?”

“What is the most realistic outcome of this situation?”

Instead of asking your brain:

“Why are you trying to sabotage me?”

Asking yourself these questions will allow you to acknowledge your anxiety without automatically believing every thought that comes with it.

HOPE

Your brain learned to look for danger because it was trying to protect you.

But you don’t have to believe every warning it sends.

The more you learn to separate possibility from probability… the less frightening uncertainty becomes.

Your brain can still protect you without convincing you that the worst is always about to happen.
