What strategies do you know for dealing with low self-esteem?

My self-worth is very low. I’ve dealt with bullying at college, and I’ve gone through group therapy (never again!). My family is dysfunctional, I can’t rely on any of my parents, and I don’t think they see me as the gifted daughter they always wanted to have. My brother is their favorite, and I’m the black sheep. Sometimes I’m painfully aware that I can’t stand for myself, and I let people treat me like a weakling. People somehow sense that I won’t resist, and they take advantage of me. I try to be a better daughter, a diligent worker, a good girlfriend. It falls apart no matter how much I try. I don't know how to change how I feel about myself.

If you’ve ever felt the same, how did you get over it and start enjoying your life? Serious replies only, please!
