Now, Hon, I'm so sorry you had to go thru all that crap. I can't totally relate to your experinece, but I have had a abusive choldhood as weel, so I know what you are against here.
Please don't be so hard on yourself. You've done great for the most part, adn if your parents aren't going to support you, well, move on and start your healing path, which I think you already did.
Pm me anytime~
