My stepdad says I have a week to get out of his house, but I can't go to my real father's house anymore because I'm now out of the closet (Not by choice) and he's a homophobe. I need to show my stepdad that even thought I've been in trouble a few times, I'm not a bad guy. But I don't know how. What should I do?
Have you sat down with your Step-Dad and just asked for a chance to prove yourself? I would explain the situation to him, tell him you're remorseful for what you've done in the past, let him know you've learned from it, and are a better person now. Hopefully that'll at least get you through the next three years until you're 18.......Good Luck, I hope it all works out for you :-/
It's only a mistake if you don't learn from it, other than that it's a learning experience. When your stepdad has cooled down, try talking to him one on one and tell him what's going on with you and how you're feeling...
Oh, and splash holy water on yourself. You're not Satan if your skin doesn't burn haha.
