So I threw up tonight, and it's the first time I've done it for probably a couple of months. Before this, I had been doing it for a few weeks, but then I stopped until tonight. I'm worried that this could be the beginning of bulimia. It's not like I throw up after each meal, or that I binge and then throw up. It's just once in a while when I feel like it. How did you start becoming bulimic? When does a person become officially bulimic rather than just being a person who throws up sometimes? Like would I have to throw up multiple times a day to have bulimia, or is the fact that I did it once mean I have it?
