Self-Esteem and Anxiety: How They Influence Each Other

Many people with anxiety carry a quiet belief that they are somehow not enough: not competent enough, not likable enough, not strong enough. This lesson looks at how that belief and anxiety influence each other, and what can be done about it.

Learning objective

By the end of this lesson, you should be able to describe the bidirectional relationship between self-esteem and anxiety, explain what core beliefs are, and try one exercise for examining a self-worth belief.

The concept

Self-esteem: a working definition

Self-esteem is your overall evaluation of your own worth. It’s not how you perform in any one area but how you view yourself as a person. People with low self-esteem tend to hold a negative global view of themselves that persists across situations, even when evidence contradicts it.

The two-way relationship

Research shows the link runs in both directions. A meta-analysis of 77 longitudinal studies by Sowislo and Orth found that low self-esteem predicted subsequent anxiety symptoms (and depression), even after controlling for prior symptom levels [1]. But the reverse was also true: anxiety predicted later declines in self-esteem.

The cycle works like this:

1. Low self-esteem → anxiety. If you believe you are inadequate, the world feels more threatening because you expect you won’t be able to cope. Ordinary challenges (a work task, a social event, an uncertain outcome) activate the threat system.
2. Anxiety → low self-esteem. Anxiety leads to avoidance and safety behaviors, which feel like failure. “I couldn’t even go to the party.” “Everyone else manages this.” Each avoidance reinforces the belief that you’re not capable.

Core beliefs: the hidden engine

Aaron Beck’s cognitive therapy model introduced the concept of core beliefs (sometimes called schemas): deep, general beliefs about the self, others and the world that develop early and act as filters for experience [3].

In anxiety with low self-esteem, common core beliefs include:

• “I am inadequate.”
• “I am weak.”
• “I am not good enough.”
• “I am unlovable.”

These beliefs are usually not conscious. Instead, they show up in patterns: the automatic tendency to interpret ambiguity as criticism, to remember failures and forget successes, or to attribute success to luck and failure to character.

Fennell’s cognitive-behavioral model

Melanie Fennell developed an influential CBT model specifically for low self-esteem [2]. The key components are:

1. A negative core belief (“I’m worthless”) forms through early experiences.
2. Conditional assumptions develop as rules for survival: “If I’m perfect, people won’t reject me.” “If I never show weakness, I’ll be safe.”
3. A trigger activates the belief — a failure, a rejection, an ambiguous social signal.
4. The bottom line is confirmed: “This proves I’m not good enough.”
5. Anxiety, low mood and avoidance follow, which prevent the person from gathering evidence that contradicts the core belief.

A worked example

The following is a fictional example used for teaching.

Amira receives an email from her manager asking to schedule a meeting. No other details.

• Core belief activated: “I’m not good enough. This must be about something I did wrong.”
• Anxiety response: racing heart, difficulty concentrating, scanning for what she might have done.
• Behavior: she prepares extensively, rehearsing defenses for criticisms that haven’t been made.
• The meeting: her manager wants to discuss a new project and is considering Amira for it.
• Filter in action: even after the meeting goes well, Amira focuses on a moment when she hesitated and wonders if the manager noticed. The positive outcome barely registers.

Amira’s core belief filtered the ambiguous email as a threat and then filtered the positive meeting to fit the existing narrative. This is how negative core beliefs maintain themselves: they bias attention, memory and interpretation.

A common misunderstanding

“High self-esteem means thinking you’re great at everything.” Healthy self-esteem is not about inflated self-assessment. It’s about holding a balanced, realistic view of yourself that includes strengths and limitations. You can acknowledge a weakness without it collapsing into a global verdict on your worth.

An exercise: the evidence log

Core beliefs are maintained because disconfirming evidence is filtered out. This exercise puts the evidence where you can see it.

Create two columns:

Evidence that fits the core belief	Evidence that contradicts it

For one week, write down events in both columns. Most people find the “fits” column fills quickly (because the filter directs your attention there) and the “contradicts” column is harder — you have to actively look.

Common entries for the contradicts column:

• A task you completed adequately.
• A compliment you received.
• A difficulty you handled without catastrophe.
• A relationship that has lasted.

The aim is not to argue yourself into high self-esteem. It’s to notice that the negative core belief is operating as a filter, not as a complete account.

A meta-analysis of CBT interventions for self-esteem found moderate improvements, supporting the idea that self-esteem beliefs are changeable [4]. A pilot randomized trial of CBT for low self-esteem in primary care found improvements in both self-esteem and depressive symptoms [6].

When to talk to a professional. Speak to a GP or mental health professional if low self-esteem is persistent, pervasive, and accompanied by low mood, withdrawal, or anxiety that interferes with your life. CBT for low self-esteem exists as a structured treatment and has been tested in clinical settings. If you’re in crisis, call or text 988 (US) or contact Samaritans on 116 123 (UK and Ireland).

Recap

• Low self-esteem and anxiety reinforce each other in a bidirectional cycle.
• Negative core beliefs about the self filter experience to confirm themselves.
• Fennell’s model describes how these beliefs maintain themselves through conditional rules and biased processing.
• An evidence log can reveal the filter at work.
