Hi,My name is Theresa,im 21 also.You seem to be in the same boat as me.Yes you most likely have an Eating Disorder.Remember though Bulimia isnt about the purging,Binge eating is what actually defines it.You are probably like me EDNOS(eating disorder not other wise specified)Its when you dont fit into one or the other.For example you purge but dont binge or you have anorexic behaviors but still have your period or are still normal weight.It doesnt mean you dont have an eating disorder.And most importantly YOU DONT HAVE TO BE 100lbs TO HAVE AN ED.Im actually slightlyover weight and purge all the time,starve myself,take laxitives and diet pills,and over exercise.But if someone one the street looked at me they would never think eating disorder.but I do.Dont mean to scare you or anything just want you to understand.If you wanna talk im allways here.
