over the past couple of months, I've been dieting quite a bit and I've lost probably about 15 pounds, although over the past 2 years I've probably lost somewhere between 30-40 pounds. These past couple of months have definitely been my most extreme dieting to date however.

I'm honestly not sure if what I'm doing constitutes an eating disorder though. I've begun to really obsess over the food I eat - I'll only eat about 600 calories or less in a day, and if I eat more I get pretty disappointed. I create meals that have the lowest calories possible, for example I'll eat mushrooms mixed with hot sauce and sugar free jello for lunch and nothing else for the rest of the day. of course I'll get hungry, so I'll drink tea, diet soda flavored water to fill me up. I'm almost always hungry, so all I think about is food I want to eat. however, if I ever get full from a meal, I get really down on myself.

a weird habit I've formed is I'll go into grocery stores and just look at the foods that I crave, like a bag of chocolates, and just read the nutritional information. I do this with almost all the food I eat, even fruits and vegetables so I can keep track of my calorie intake.

every once in a while I can't ignore a craving for something, however when I fulfill this craving, I'll go overboard. for example, today I ate almost a whole jar of peanut butter and afterwards I wanted to throw it up, but I find it impossible to make myself throw up, (and believe me I've tried), so I'll go for a jog or a couple mile long walk to make myself feel better.

I also excersize about an hour a day and walk a few miles a day.

to give you an example of my size, I'm about 5'5" and 118 lbs.

any input is helpful.

thanks
