I've been forcing myself to not eat. The longest period of time I've gone without eating is 5 days. The first day, I weighed myself, and I was 130 lbs. By the fifth day, I was 122 lbs. I felt like I had accomplished something. Now, I routinely weigh myself, and get extremely afraid when I see any weight gain. I don't eat breakfast or lunch, but I'll sometimes eat dinner when necessary. Everything went so well until I ate 2 serving sized meals in 1 day. I gained 2 lbs, and felt disgusted. How could I let myself eat so much when I knew the calories would make me gain weight? Because of that, I keep myself limited to 100 calories a day. Sometimes I want to eat, but the fear of gaining weight always makes me change my mind. Watching my weight drop makes me feel so happy. But, do tell, is this some type of eating disorder, or is it something else?
