Why Do I Keep Second-Guessing Myself?
Understanding Ambivalence, Anxiety, and the Exhaustion of Constant Decision-Making
A blog by Mindful Insights Psychotherapy – Psychotherapy and Counselling in Mississauga, Ontario
Have you ever made a decision… only to immediately question it?
You choose something, and then your mind starts spinning:
“Was that the right choice?”
“Maybe I should’ve done the other thing.”
“What if I regret this later?”
And sometimes, the decision itself isn’t even that big.
What to text back.
What job to take.
Whether to stay or leave.
What to order.
Whether you upset someone.
Whether your feelings are “valid enough.”
At Mindful Insights Psychotherapy, a psychotherapy practice in Mississauga, Ontario, many people entering therapy for anxiety, overthinking, stress, trauma, or self-esteem concerns describe this exact experience.
Not just difficulty making decisions.
But exhaustion from constantly doubting themselves, revisiting choices, and mentally replaying every possible outcome afterward.
And despite what many people assume, this pattern is often not about being “indecisive.”
It’s often about anxiety, emotional overload, and a nervous system that no longer feels safe trusting itself.
Ambivalence Is More Human Than People Realize
Most people think decisions should feel clear.
Confident.
Certain.
But psychologically, human beings are capable of holding conflicting emotions at the same time.
You can:
want closeness and fear vulnerability
want change and fear uncertainty
want rest and feel guilty slowing down
want reassurance and fear depending on others
This internal conflict is called ambivalence.
And ambivalence is not dysfunction.
It’s part of being human.
The problem begins when your nervous system starts treating uncertainty like danger.
Because then, every decision starts feeling emotionally loaded.
Why Anxiety Makes Decision-Making So Difficult
From a mental health and neuroscience perspective, anxiety increases the brain’s need for certainty.
Your mind starts trying to predict:
what could go wrong
how other people might react
whether you’ll regret your choice
how to avoid discomfort completely
But life does not offer perfect certainty.
So the brain keeps searching.
And searching.
And searching.
This is why many people struggling with anxiety feel emotionally stuck between options, even after they have technically already made a decision.
Your brain is trying to eliminate risk entirely before allowing you to feel settled.
The problem is:
No decision can provide that level of emotional guarantee.
Sometimes Changing Your Mind Is About Fear, Not Preference
Many people assume:
“If I keep changing my mind, I must not know what I want.”
But often, the issue is not lack of desire.
It’s fear of the emotional consequences attached to the choice.
You may notice thoughts like:
“What if this hurts someone?”
“What if I make the wrong decision?”
“What if I disappoint people?”
“What if I regret this forever?”
“What if this says something bad about me?”
From a trauma-informed therapy perspective, decision-making can become extremely difficult when past experiences taught you that mistakes were unsafe.
Maybe:
criticism was harsh growing up
mistakes led to shame
conflict felt emotionally overwhelming
you were expected to “get things right”
your needs were minimized or ignored
Over time, the nervous system learns:
“Choosing wrong is dangerous.”
So instead of making decisions freely, you start managing anxiety around consequences.
Decision Fatigue Is Real
Another important piece here is emotional and cognitive exhaustion.
Many people seeking therapy for stress, burnout, anxiety, or emotional overwhelm are already mentally overloaded.
You may spend much of your day:
overthinking
managing responsibilities
emotionally monitoring others
worrying about outcomes
suppressing your own needs
making constant small decisions
Eventually, the brain becomes depleted.
This is called decision fatigue.
And when the brain is exhausted, even small choices can start feeling overwhelming.
You may notice:
difficulty committing to decisions
changing your mind repeatedly
constantly wanting reassurance
feeling mentally “stuck”
avoiding decisions altogether
Not because you are incapable.
But because your system is tired.
Why You Might Constantly Ask Other People What They Think
When self-trust feels shaky, reassurance becomes incredibly tempting.
You may frequently ask:
“What would you do?”
“Do you think I made the right choice?”
“Am I overreacting?”
“Does this make sense?”
This is often an attempt to borrow certainty from other people.
And while reassurance can feel calming temporarily, it can unintentionally reinforce the belief that you cannot trust your own judgment.
Over time, this creates even more self-doubt.
The Hidden Fear Beneath Indecisiveness
When we slow this pattern down in therapy, there is often a deeper fear underneath it.
Not just fear of the decision itself.
But fear of:
regret
judgment
rejection
failure
responsibility
emotional discomfort
being blamed
disappointing others
In many cases, changing your mind is less about confusion…
And more about trying to avoid emotional pain.
Why Insight Alone Doesn’t Always Help
You may logically understand:
“There’s no perfect choice.”
And still feel completely overwhelmed making one.
That’s because this pattern is not just cognitive.
It’s nervous system-based.
Your body may still react to uncertainty as if something emotionally dangerous is happening.
So even simple decisions can create:
tension
anxiety
overthinking
emotional paralysis
This is why “just trust yourself” is often not enough.
Self-trust is not built through pressure.
It’s built through safety, experience, and learning that you can survive imperfect decisions.
What Therapy Can Support (Without Overpromising)
At Mindful Insights Psychotherapy in Mississauga, we approach anxiety, overthinking, self-doubt, and emotional overwhelm with care and ethical clarity.
Psychotherapy does not:
eliminate uncertainty from life
guarantee perfect decisions
stop overthinking overnight
remove all regret or fear
But therapy can support:
understanding why decisions feel emotionally loaded
identifying anxiety and shame patterns
recognizing when overthinking becomes paralysis
building emotional tolerance for uncertainty
strengthening self-trust gradually
reducing the intensity of rumination and second-guessing
Over time, many people notice something subtle but meaningful:
They stop needing every decision to feel perfect before moving forward.
A More Helpful Question to Ask Yourself
Instead of asking:
“What if I make the wrong choice?”
Try asking:
“What choice feels most aligned with who I am right now?”
Or:
“Am I trying to make the perfect decision… or a human one?”
Those questions shift the focus away from fear and toward self-awareness.
A Final Reflection
If you constantly second-guess yourself…
If every decision feels emotionally exhausting…
If you replay choices long after they are made…
You are not weak.
You are not incapable.
You are not “bad at life.”
You may simply have a nervous system that learned uncertainty feels unsafe.
At Mindful Insights Psychotherapy, we support individuals exploring therapy for anxiety, overthinking, stress, burnout, and emotional overwhelm in a way that is grounded, paced, and ethically aligned.
Because healing is not about becoming perfectly certain all the time.
It’s about learning that you can still trust yourself…
even when certainty does not exist.
And that kind of trust is built slowly,
one imperfect decision at a time.
