First of all - Welcome to AS!
You are so brave for sharing that and I'm so sorry you have endured all that. You are so strong and a survivor of so much. I'm so sorry all these people treated you like that and hurt you. But you did not do anything to deserve it and you are in no way at fault for any of it. The blame goes to those who hurt you. You did NOTHING wrong and you did not get yourself into these situations. I know that's probably hard to believe but you are not to blame. Again I'm so sorry this happened. I don't see you as being selfish, I see you as being brave, strong, and courageou
