Building Self-Esteem: A Psychologist’s Guide
Self-esteem is your overall sense of your own worth. Healthy self-esteem isn't about thinking you're better than others or feeling confident all the time. It's a steady baseline sense that you're acceptable as a person, even when you make mistakes. Low self-esteem usually has roots in earlier experiences, and it can be rebuilt through a combination of changing how you talk to yourself, changing what you do, and understanding the deeper beliefs underneath.
Signs of low self-esteem
a harsh inner critic that points out every flaw
dismissing compliments or achievements ("anyone could have done that")
comparing yourself unfavourably with others
difficulty saying no or asserting your needs
avoiding challenges for fear of failing or being exposed
over-apologising
perfectionism, where anything less than flawless feels like failure
staying in relationships or jobs that don't treat you well
depending on others' approval to feel okay
Low self-esteem isn't a mental health diagnosis on its own, but it's closely linked with anxiety, depression, people-pleasing and perfectionism.
Where low self-esteem comes from
Most people with low self-esteem can trace it back to experiences that taught them something about their worth. Common roots include:
harsh criticism, punishment or neglect in childhood
love that felt conditional on achievement, good behaviour or being easy
bullying, exclusion or being "different"
growing up in a family under stress, where your needs came last
traumatic experiences
belonging to a group that is devalued or discriminated against
From these experiences, people form core conclusions about themselves, such as "I'm not good enough", "I'm unlovable" or "I'm a burden". CBT researchers such as Melanie Fennell describe this as the "bottom line": a central belief that everyday thoughts and behaviours are organised around.
The schema therapy view
Schema therapy, developed by Jeffrey Young, offers a useful lens. It describes "early maladaptive schemas", deep patterns that develop when core childhood needs (such as safety, acceptance and autonomy) aren't met. Schemas especially relevant to self-esteem include:
Defectiveness/shame: the belief that you're flawed, bad or unworthy at your core
Failure: the belief that you're fundamentally less capable than others
Unrelenting standards: the belief that you must meet very high standards to avoid criticism
Subjugation: suppressing your own needs to avoid conflict or rejection
Schemas feel like truths rather than beliefs. That's why simply being told "you're great" rarely shifts them. You can read more in our schema therapy explainer.
How low self-esteem keeps itself going
Low self-esteem is maintained by a loop:
A situation triggers the core belief (a work review, a social event).
You predict failure or rejection.
You protect yourself by avoiding, over-preparing or people-pleasing.
If things go well, you credit the safety behaviour, not yourself. If they go badly, it confirms the belief.
The belief stays intact.
Practical strategies that help
Notice the inner critic, and name it
Start catching self-critical thoughts. Writing them down for a week can be revealing. Naming the voice ("There's the critic again") creates a little distance, which is a core ACT skill.
Ask what you'd say to a friend
If a friend made the same mistake, what would you say to them? Most people are far kinder to others. Practising that same tone with yourself is the foundation of self-compassion, which research suggests is a more stable basis for wellbeing than self-esteem built on achievement.
Keep a positive data log
Low self-esteem filters out evidence that doesn't fit. Each day, write down three things you did, handled or contributed, however small. Over weeks, this counters the filter.
Test your predictions
If you believe "If I say no, people will be angry with me", test it with a small, low-stakes no. Record what actually happens. This is behavioural experimentation, a core CBT tool.
Act according to your values, not your fears
Ask what matters to you (connection, creativity, honesty) and take small steps in that direction even when self-doubt shows up. Confidence tends to follow action, not the other way around.
Set boundaries
Letting people treat you poorly reinforces the belief that you don't deserve better. Practising boundaries is covered in our article on people-pleasing and boundaries.
Look after the basics
Sleep, movement, time outdoors and social connection all affect how you feel about yourself. They're not a cure, but they make the rest easier.
When to get professional help
Consider speaking with a psychologist if:
self-criticism is constant and harsh
low self-esteem is holding you back at work or in relationships
it's linked with anxiety, depression, disordered eating or trauma
you've tried self-help strategies and the beliefs haven't budged
Therapy helps by working at both levels: practical skills for day-to-day thoughts and behaviour, and deeper work on where the beliefs came from and what you needed that you didn't get.
