Hi, I had to reply to your message. This eating and throwing up is an eating disorder called bullimia (I think that's how you spell it). My cousin had this, before she went anorexic and ended in a hospital, she's 5'6", and was weighing at about 100 lbs., she was in the brink of death. She has gained about 15 lbs. now, and she's gaining more now. She says she regrets it so much now.
Please don't do this anymore, it's very dangerous.
