I really hope things will get better for you, too. You've been through a lot, you sound like a really strong person. Also, I can relate to seeing old pictures of yourself, and seeing how skinny you used to be.. It is pretty horrible. :/
I'm in high school, btw. Still young, so I live with my sister and see her everyday. Sometimes, I wish she'd just move out. But most of the time, it helps me feel better to just focus on making myself a better person. I believe that if I am happy with myself, inside and out, this ED can come to an end, because I won't feel like I have to compare myself. Thanks for telling me your story. Hopefully, things will get better for the both of us.
