Hang in there... I used to throw up too, but not as often as you. The most days in a row that I threw up was probably 5. Then I'd stop for a while then start up again. Then weeks would pass without me doing it. Sometimes months. So I can't exactly say I have a serious eating disorder. I do know about the urges, though. To just do something self-destructive just to say that you did something. Sometimes I just get overwhelmed by god knows what and I feel like I have to scream or cut myself or punch myself in the face. Sometimes throwing up helps, too, but it's just not something I do as often as the others.
I used to be overweight so I know what it feels like not to be happy with one's appearance. I think this was one of the main reasons for my depression and self-injuring. I just couldn't think of myself as something beautiful or worth looking at or being around. Now I go to the gym though and have reached a healthy weight and what I realized was that it was easy. Not because the workouts weren't hard or the diet wasn't too restrictive (in fact, my nutritionist made me eat more calories than I used to when I was overweight, and that helped a lot). I guess I found it easy because I didn't think, "Oh, I have to do this because I want to lose weight. It will be embarrassing if I don't." I just didn't think about it, but I kept at it. I didn't enjoy it or hate it; I just did it. And it worked, and on some level I think I was happy that I wasn't too happy or excited about the results, because it was like I had come to love myself as a person with a personality--not just a thin person. I think the sooner you realize this and start to love yourself and know you're a good person, being happy with yourself and getting healthy will become easier to achieve.
Good luck <3
