Summarize:

It can be really hard to realize that you have low self-esteem, but you may be more likely to be codependent if you don't recognize your worth. You might have low self-esteem if you’re overly critical of yourself, you think negatively of yourself and your life, and you think others are better than you. Although these messages aren’t true, they can be really painful and may make you stay in a bad relationship. If you might have low self-esteem, try to focus on your strengths and talk kindly to yourself.Typically, low self-esteem starts in childhood or happens after a painful event. It’s not your fault, and you can get better.
Look for signs you may have low self-esteem.
