Thanks for your comments guys, they really make me feel better about everything. Even though it's going to be a bit scary on my own I cant wait to get out of this house, ive been wanting to leave for years.

I hope we can keep our communication going and that i can manage to keep that one parental relationship unlike they did with their parents. I am also really hoping that when my sister moves out, she leaves my dad. She has always said she would and when shes not with him she's a lot happier and more pleasant to deal with.

I have a good relationship with my sister so if worse comes to worse, i've got her. I've told her about my unpleasant thoughts and she tells me i'm being to hard on myself but she says she understands.
