Skinny vs. Anorexia

Hi! I just turned 16 years old about a month ago and I currently weight 88 pounds and am 5ft 3in. I have a skinny build. I am starting to get worried about eating disorders, especially anorexia, because I am obsessed with calories and excercising. I bike at least 5 miles everyday, run everyday, and am constantly working my abs (core). I am scared that I will gain weight because I like being this small. I also haven't had my period for 8 months and am kind of freaked out. I don't like talking about eating disorders because I am scared of them and am worried that I will have to go to the doctor. I don't want to gain weight but do I have to?
Am I anorexic or just really skinny? (I can't be bulimic because I have never thrown up). Please tell me what is going on with me! I don't want to have an eating disorder!

That weight is not healthy for your age or size.  You are obsessed with calories and working out which is a sign of anorexia, plus you are afraid of gaining weight.

Please get help before it escalates and its too late.  

Accepting that you are anorexia is a hard thing.  

I am 33yrs old and I recently accepted that I was bulimic and I have been dealing with it over the last year. Its hard but its easier because I have accepted that I have a problem.

Good luck :)
