Slayguy138: I don't think you came across as selfish at all. Everyone here is talking about their childhoods, and you had a lot to say about yours. It's good to talk about it, I think, when you're able to.
As for OD-ing, I can tell you from personal experience, OD-ing on pretty much anything suuucks. It feels like you're dying. Be glad you never started using, because all it does is ruin your life, or at best give you yet another problem to juggle.
Aspergers is a terrible thing to have to deal with, especially when your parent makes it harder for you. My ex husband has aspbergers, and a supportive parent, and it is still hard for him, so I can't imagine what it's been like for you. Real friends, though they can be few and far between, are understanding and wouldn't care if you broke some stupid social rules. Personally, I choose to be around other people who are socially awkward because they won't mind when I suddenly start talking to myself or get distracted in the middle of a conversation or a sentence. Maybe you can find others like that where you are too. I don't know if any of this is helpful, but hang in there, and don't apologize! You haven't done anything wrong.
