Your self esteem can be changed, however, by you - by the decisions you make and the actions you take. This page explains some of the things you can do to improve your self esteem.
You can get low self-esteem if, instead of positive reinforcement, the messages you were given were negative ones. You then grow up believing that you are worthless. This is not not true, but you end up believing it - that is, you end up believing a lie.
Take a realistic, balanced view of your self in comparison to others. People with low self esteem see themselves in an unduly negative light, and others in an unduly positive light. The truth is much more balanced than that. There is much about you that is good. None of us is perfect.
Get people to give you positive feedback, where appropriate.
Or spend time with people who offer it to you without asking.
Treat yourself with respect and don't dismiss praise and recognition.
Say "thank you" when you are complimented or praised.
Don't let other people make you feel bad.
Don't accept "put downs" from others.
Remember, no matter what other people say (when they are suffering from low self and try and take it out on you): you are some of significant self-worth. Start believing it, and start behaving as if it is true (because it is true).
