I am 15 years old and am overweight I want to be bulimic or anerexic please help I will stop when I get to the weight 100 lbs.

Both bulimia and anorexia are EXTREMELY bad for your health and NOT to be even considered.

You need to rethink your food intake and start working out.
Losing weight and keeping it off involves a change of life style.
There are NO quick fixes.

I'm sorry, but we are not going to tell you how to kill yourself.
