I'm bulimic but I want to get better?

So i've been been an on again off again bulimic for a little less then a year but I'm really starting to get scared. I want to help myself, and please don't tell me to tell somebody about it, I really am not up for that right now. Do you know of any websites or advice that can help me, I'm starting to hate myself for this more and more and want to get better.
