I think if you're not in IMMEDIATE danger of dying like from bulimia or anorexia, "they" don't call it an ED. Even if you have morbid obesity, morbid meaning deathly, you can't have an "active" ED going into gastric bypass surgery. Personally, I think your ups and downs sound painful, and they sound too familiar to me. People advised me to get this under control when I was still young because it only gets harder. Easy for them to say! My advice, from experience, would be to find a sport OR TWO OR THREE. You will start off doing the sport to lose weight, then losing weight to do the sport better. And having a lot of fun and making new friends on the way and REALLY changing your life for the better, and making the best memories of your life. Your ability to track calories etc can be an asset.
