I think i have bulimia!?

You are developing bulimic behaviors. Being a recovering bulimic, I know how it feels. Once you start, it's very hard to stop the behaviors. What I've learned is not to eat food then throw it up, but to chew the food thuroughly then spit it out before you swallow it. That way you're not tempted to throw it up. But you definately should seek help so you can have a healthy diet
