I've had bulimia 16 years, last night i vomited a piece of what i believe was stomach or esophgus tissue, and then was spitting blood- possible?

Get to a Dr!: You need to have an exam as soon as possible to discover what's going on. Yes, long term severe bulimia can damage your G.I. tract - it's serious. You also need to find an effective Eating Disorder Psychologist or program to correct this disorder. It's not easy, but it is possible and it is life-saving! Please - it's already been too long and will only get more difficult if you wait. Get help.
