Have you ever met someone who was always bragging about their big bank account, killer career, or endless love for their partner? This person may seem like they have it all, but that’s because they are hiding a secret: they are insecure. People who are insecure seek reassurance from others and tend to have an extremely low self-esteem. They are afraid of rejection and abandonment and create problems in their relationships by taking everything personally, misinterpreting their partners’ behaviors or statements, or reacting irrationally.

Insecurity can also manifest as perfectionism, which leads to a constant need for perfection and harsh self-criticism, says Glickman. It can also lead to jealousy and envy of other people, and a fear that you are not good enough. Insecurity is common and can have a negative impact on your relationships, work, school, self-esteem, and mental health. It can be difficult to identify and change, but a therapist can help you overcome it with lifestyle changes and shifts in perspective.
