About a year ago, I lost 26 pounds over the course of several months simply by cutting calories. I, of course, did this in a safe way and did not starve myself. Now that I am thin and happy with my body, I obsess over weight gain all the time. After I eat I feel guilty and wish I hadn't eaten so much. I also get really depressed when my clothes fit just a little bit snugger than usual. I'm constantly stepping on the scale, and cannot sleep at night because I keep recounting the uneccessary calories I consumed throughout the day.
