ive been bulimic for about 5 months. im 5'2 and i maintained my weight around 104-106 pounds. during this time i would stop purging and eat around 1200 calories and still maintain my weight at 105 but always relapse. recently ive stopped purging and stick to a 1200 calorie diet but my weight shot up to 110. why is this happening now and not before? how do i get my weight back to 105 again?

i also realized that my stomach is a different shape but i still fit into jeans/shorts from when i was 104-106 pounds and purging
