I am feeling resentful towards my parents because of my childhood?

When I read the title to your "problem" I thought it was over something serious, I stopped reading after I realized what it was about. I am feeling resentment of my mom because she gave me away to foster care at your age because she didn't want me. Try getting over that. Realize, that your worst problem is that your parents provided you with food, a roof over your head and love, I would have killed for that.
