What can i do to better my self esteem?

Act on values: Act according to your values, time after time. Set small goals, and meet them. Break larger goals down into doable portions, and get there step by step. As you live up to your own values and goals, your view of yourself becomes more positive. "i am a person who gets up and gets a shower in the morning." "i pay my bills on time, " etc. Avoid those who belittle you. Psychotherapy helps too!
