Of course its a bad thing. Having an eating disorder is never fun. I've had one before, and it takes strength that I never had to come out with it. So good on the first step. Second is getting help. This is confusing to a lot of people who've had ED's for a long time. They don't know what to do, how to handle it, etc.
Here's something to think about: bulimia is a mental disease. That's why people underestimate it alot of times. Its not something you just stop doing out of nowhere. The main thing about overcoming it is jumping that mental hurdle. Once you do that, its so much easier.
When you look in the mirror, smile at yourself. You're not fat. Hug yourself. Have self confidence. You're truly a beautiful girl. You've had road blocks in life, and you've overcome them.
Find the root of the problem. Eating disorder's, all of them, have a root. Mine was my mother's emotionally abusive tendicies. I realized it didn't matter what she thought about me, only my opinions truly mattered. Once you find it, come to peace with it. Lots of times it can't be eradicated, but you can eradicate the problem aspect of it. I can't kill my mother, but I killed the impact she made on me.
If you can't, there's always rehab. They'll help you more. Professionals help can help some, while others do better on they're own.
I wish you the very best of luck with this. :)
