I agree that bulimia and SI are symptoms of the same thing. Part of it is emotional invalidation and not having better ways to cope.

A good book to gain some insight into the whole thing is "Women Who Hurt Themselves" by Dusty Miller. It's about all of the ways that we hurt ourselves, including SI, eating disorders, addiction, and anything else that hurts us. And it also helps you to know how to start recovering.
