I know when I wasn't eating & then I would try to eat, I would feel nausea. The nausea was causing me not to eat because I can't stand to throw up. So any time I feel nausea, I don't eat. That could be why you are throwing up after not eating.....rather than it being bulimia.

What ever is going on, you have a problem that needs professional help & your parents need to be the ones to get you the help you need......but you need to be open to the help & want it for it to do any good.

You are harming your body in the future if you get that far......that is a consequence that you will more than regret when it happens.......You need help with your body image....from what you have said......12 years old & 83 pounds....is definitely being anemic. I am surprised that you aren't passing out all the time.....I know when I was at that point, that was what was happening to me.

You need help....& you need to want help,
Debbie
