I think I may be getting an eating disorder...?

I grew up a little fat kid and was made fun of by most of the people I knew. My family was torturous with their petty remarks. So since 4th to mid way through my 11th grade year I was obese...I decided to go to extremes to loose weight. I ran 8 miles a day during my winter vacation and went from 250lbs to 195lbs just during that winter. Then during school I got into running and then stopped eating fast food and eating sweets. By my senior year I got to a healthy 145lbs...I was in bliss. That was in 2006 and now I weigh 155 and have gained muscle m. but I have been vegetarian for 3 1/2 yrs and I do not eat pastas, breads, potatos or gelatin. I have gotten to the point where I hardly do consume a full meal. I hide this well, my family does not notice.
