I'm so sorry. You must be incredibly strong to get through all that. Nobody should have to, and it's normal that you feel depressed; who wouldn't? The only advice I can give you is never go into a room with any guy like your cousin alone. Ever. And remember that the problem is not you. You sound like a great person who's had a whole bunch of bad stuff happen to her, but you're getting through it. You deserve a chance at a good life, and I know you can make it through this. I'm always here if you need anything, always feel free to PM
me. Stay strong!
