Read the Book "Toxic Parents" by Susan Forward besides therapy this really helped me see what a codependent relationship I had with my own parents. They thrive on making me the victam. It is not worth the pain. I see my parents a couple times a year now and keep it at that. When I was going over there several times a month I was depressed as I kept getting sucked into there games. And it is a game. 3 years of therapy later and my mother can still make me cry. The last time I seen her was Easter were I told her I was pregnant. She just gave me the dirtest look. I havent seen her since especially since I miscarried and I dont want her to rub it in as I know she did not want me to have children. I still love my mom and dad but I choose to live my life and not them threaten my mental sanity any longer. I dont know why but I find if I email my mom here and there I am better off keep it short and simple. I love her but I dont like her if you understand that.
Anyways try the book it is really good. Also I tried Codependents Anonymous also known as CODA it is a support group. Excellent.
Sorry you are feeling this way I know what it is to be the black sheep in the family and I took there power away and I have been feeling better.
