Self-Doubt Can Feel Exhausting: What Might Be Going On?
Understanding self-doubt, anxiety and the need for reassurance
Do you ever find yourself replaying conversations in your mind, wondering if you said the wrong thing, came across badly, or upset someone without meaning to?
Perhaps you send an email and then question the tone or worry whether somebody will reply. Maybe you second guess decisions, look for reassurance from others, or feel stuck in a cycle of overthinking.
You may find yourself wondering:
Why do I doubt myself all the time?
Why do I always think I have got something wrong?
Why can I not trust my own judgement?
In many ways, questioning ourselves from time to time is part of being human.
We all reflect on situations or wonder whether we could have handled something differently.
However, when self-doubt becomes relentless, it can begin to feel exhausting.
For many people, it can feel like an unwanted visitor sitting quietly on their shoulder, constantly questioning, criticising, and looking for signs that something has gone wrong.
Instead of occasional reflection, the mind can become stuck in a loop of questioning:
Did I say the wrong thing?
What if they took that the wrong way?
What if they think badly of me?
Over time, these repeated worries can begin turning into internal messages we carry about ourselves:
I always get things wrong.
People probably find me annoying.
I am not good enough.
When this happens, self-doubt is no longer only about the situation in front of us. It can begin affecting confidence, relationships, and how we see ourselves.
When Self-Doubt and Anxiety Become Tangled Together
Self-doubt and anxiety often become closely linked.
The more anxious we feel, the more we may replay conversations, imagine worst-case scenarios, or worry about how others see us.
For many people, this naturally leads into seeking reassurance.
Or perhaps you find yourself checking, overexplaining, apologising, or avoiding situations altogether because the fear of getting something wrong feels too uncomfortable.
In the moment, these responses can help us feel calmer.
However, reassurance or avoidance often eases anxiety only temporarily. Before long, the self-doubt returns and the cycle quietly begins again.
Why Do I Keep Seeking Reassurance?
Self-doubt can become closely linked to anxiety and our natural survival responses.
When we feel under threat — even emotional threat such as criticism, rejection, conflict, or fear of getting something wrong — our body may move into what is often called a fight, flight, freeze or fawn response.
These responses are often ways of trying to feel safe.
Self-doubt may show up differently for different people:
- Flight – overthinking, replaying conversations, trying to get things “right”, or seeking reassurance.
- Freeze – avoiding situations, struggling to make decisions, procrastinating, or feeling stuck.
- Fight – frustration, defensiveness, or a harsh inner critic.
- Fawn – working hard to keep people happy, avoiding conflict, or worrying deeply about upsetting others.
None of these responses mean there is something wrong with you.
They are often ways of coping when something feels emotionally unsafe.
For many people, reassurance can feel especially important.
You may find yourself asking:
“Do you think I upset them?”
“Was that okay?”
Or perhaps you quietly seek reassurance through checking messages, replaying conversations, apologising, or looking for signs that everything is okay.
In the moment, reassurance can feel comforting.
Anxiety settles, even if only briefly.
However, when self-doubt runs deep, reassurance often does not last for long.
Before long, another worry appears. Another interaction is replayed. Another doubt creeps in.
Over time, we may begin trusting reassurance from others more than our own instincts, which can make it harder to build confidence in ourselves.
This does not mean seeking reassurance is “bad” or something to judge ourselves for.
We all need support and connection at times.
However, part of moving through self-doubt may involve slowly learning to trust ourselves again.
Not perfectly. Not all at once.
But perhaps beginning to notice:
What feels familiar here?
What has been triggered?
Can I respond to myself with curiosity rather than criticism?
Why Do I Doubt Myself So Much?
There is no one answer.
At times, self-doubt may connect to anxiety or fear of judgement.
For others, it may link to earlier experiences, relationships, or messages absorbed over time.
Perhaps you grew up feeling pressure to get things right or learned that making mistakes did not feel safe. Maybe criticism, rejection, or difficult experiences shaped how you came to see yourself.
Over time, repeated self-doubt can begin affecting how we see ourselves.
For some people, the fear of getting things wrong slowly becomes tied to deeper beliefs:
Maybe I am not good enough.
Maybe people will reject me.
Maybe I cannot trust myself.
If this feels familiar, you may also relate to my previous blog, “Always Feeling ‘Not Good Enough’? What Might Be Going On?”, where I explore self-worth, inner criticism, and the messages we can carry about ourselves.
How Self-Awareness Can Help
Self-awareness can be incredibly helpful.
Taking time to understand our thoughts, feelings and patterns can help us begin making sense of ourselves. In many ways, self-awareness can support greater understanding and self-trust.
Self-awareness is not about criticising ourselves or endlessly analysing every interaction.
Instead, it can help us become curious:
Why did that situation affect me so much?
What was happening for me there?
Why do I find criticism or rejection so difficult?
What might sit underneath this fear of getting things wrong?
Over time, understanding ourselves more deeply can help us notice patterns, respond with greater compassion, and slowly begin building trust in ourselves again.
When Might Counselling Help with Self-Doubt and Anxiety?
Most of us question ourselves from time to time. That is part of being human.
However, when self-doubt begins affecting confidence, relationships, work, social situations, or everyday life, it may help to explore what is happening underneath.
Counselling can offer a space to slow things down, make sense of patterns, and begin understanding where self-doubt, anxiety, overthinking, or fear of judgement may have come from.
Rather than trying to “fix” yourself, counselling can be about building understanding, self-awareness, and a kinder relationship with yourself.
A Final Thought
If self-doubt feels exhausting, you are not alone in this experience.
Questioning ourselves is part of being human.
However, when the inner questioning becomes relentless, it may be worth gently asking:
What might be going on underneath this?
Self-doubt can feel lonely and exhausting, yet often there is a reason these patterns developed.
Sometimes, understanding ourselves more deeply can help us move from criticism towards curiosity, and slowly begin trusting ourselves a little more.
