Low self-esteem can manifest in subtle yet significant ways, affecting not only an individual’s mental health but also their relationships, career, and overall quality of life. Recognizing the signs of low self-esteem is crucial for offering support or seeking help when needed. In this article, we’ll explore 10 red flags that scream a person has low self-esteem, backed by expert insights and credible sources. Let’s dive in.
Understanding Low Self-Esteem: Why It Matters
Self-esteem refers to how we perceive our worth as individuals. People with healthy self-esteem tend to feel confident, capable, and deserving of respect. On the other hand, those with low self-esteem often struggle with feelings of inadequacy, self-doubt, and unworthiness. According to the American Psychological Association (APA), low self-esteem is linked to mental health challenges such as anxiety, depression, and even substance abuse (source ).
Identifying the warning signs early can make a world of difference. Below are 10 red flags that may indicate someone is struggling with low self-esteem.
Constant Need for Validation
Seeking Approval from Others
One of the most prominent signs of low self-esteem is an excessive need for external validation. Individuals who constantly seek approval from others—whether through social media likes, compliments, or reassurance—often lack confidence in their own abilities. This behavior stems from a fear of rejection or failure, which can create a cycle of dependency on others’ opinions (source ).
For example, someone might post frequent updates on social media and obsess over the number of likes or comments they receive. While occasional validation-seeking is normal, relying on it excessively can be a red flag.

Over-Apologizing for Everything
Saying “Sorry” Too Often
People with low self-esteem often apologize unnecessarily, even when they haven’t done anything wrong. They may say “sorry” for minor inconveniences, like bumping into furniture or expressing an opinion, out of fear of being perceived as bothersome or offensive.
This habit reflects a deeper issue: an inability to assert themselves and recognize their inherent value. According to Psychology Today, over-apologizing can erode one’s sense of self-worth and reinforce feelings of guilt or shame (source ).
Avoiding Challenges or New Opportunities
Fear of Failure
Individuals with low self-esteem often shy away from taking risks or trying new things due to a fear of failure. They may believe they’re not good enough to succeed, leading them to avoid opportunities altogether. For instance, someone might decline a promotion at work because they doubt their skills, even if they’re fully qualified.
This avoidance behavior can hinder personal and professional growth, trapping individuals in a comfort zone that limits their potential. Research shows that fear of failure is closely tied to low self-confidence and can perpetuate a cycle of stagnation (source ).

Negative Self-Talk
Criticizing Themselves Harshly
Negative self-talk is a hallmark of low self-esteem. People who engage in this behavior frequently criticize themselves, focusing on their flaws rather than their strengths. Statements like “I’m so stupid” or “I’ll never get it right” reflect deep-seated insecurities and a lack of self-compassion.
The National Institute of Mental Health highlights that persistent negative self-talk can contribute to anxiety and depression, making it essential to address this pattern early (source ). Encouraging positive affirmations and self-kindness can help counteract this harmful habit.
Difficulty Accepting Compliments
Dismissing Praise
When someone with low self-esteem receives a compliment, they often dismiss or downplay it. For example, if told they did a great job on a project, they might respond with, “Oh, it wasn’t that big of a deal,” or “Anyone could have done it.”
This reluctance to accept praise stems from a belief that they don’t deserve recognition. Over time, this behavior reinforces their negative self-perception and prevents them from acknowledging their achievements.

Overly Critical of Others
Projecting Insecurities
Another red flag is being overly critical of others. People with low self-esteem sometimes project their insecurities onto those around them, nitpicking flaws or finding fault in everything. This behavior serves as a defense mechanism to deflect attention from their own perceived shortcomings.
According to Harvard Health Publishing, excessive criticism of others can strain relationships and create a toxic environment, further isolating the individual (source ). Addressing underlying insecurities is key to breaking this cycle.
Social Withdrawal
Isolating Themselves
Social withdrawal is a common sign of low self-esteem. Individuals may avoid social gatherings, cancel plans last minute, or spend excessive time alone due to feelings of inadequacy or fear of judgment. They might worry about saying the wrong thing or being rejected, leading them to isolate themselves instead.
Prolonged isolation can exacerbate mental health issues and reduce opportunities for meaningful connections. The Mayo Clinic emphasizes the importance of addressing social withdrawal to prevent loneliness and its associated risks (source ).
Perfectionism
Setting Unrealistic Standards
Perfectionism often masks low self-esteem. Individuals set impossibly high standards for themselves, believing that anything less than perfect is unacceptable. When they inevitably fall short, they experience intense disappointment and self-criticism.
While striving for excellence can be motivating, perfectionism driven by low self-esteem can lead to burnout, stress, and dissatisfaction. Experts suggest practicing self-compassion and embracing imperfection as part of the human experience (source ).
Comparing Themselves to Others
Falling Into the Comparison Trap
Constantly comparing oneself to others is another red flag of low self-esteem. Social media platforms amplify this tendency, as users are bombarded with curated images of success, beauty, and happiness. People with low self-esteem may feel inadequate when measuring their lives against these unrealistic standards.
The American Psychological Association warns that excessive comparison can harm mental health and diminish self-worth (source ). Limiting screen time and focusing on personal growth can help combat this destructive habit.
Reluctance to Express Needs or Set Boundaries
Struggling to Advocate for Themselves
Individuals with low self-esteem often struggle to express their needs or set boundaries in relationships. They may fear conflict or rejection, leading them to suppress their feelings and prioritize others’ happiness over their own.
This inability to advocate for oneself can result in resentment, emotional exhaustion, and unbalanced relationships. Learning to communicate assertively and establish healthy boundaries is crucial for building self-respect and improving interpersonal dynamics (source ).
Conclusion
Recognizing the red flags of low self-esteem is the first step toward fostering healthier self-perception and relationships. Whether you’re observing these behaviors in yourself or someone else, understanding their root causes can pave the way for meaningful change.
If you or someone you know is struggling with low self-esteem, consider seeking professional guidance. Therapy and counseling can provide valuable tools for building confidence and overcoming insecurities. Remember, self-esteem is not fixed—it can grow and evolve with effort and support.
