Tamarino, all I can say is, I’ve been there. You are the picture of a person with an eating disorder. The reason you get a puffed up face is water retention (edema), which is a healing mechanism for the body. You are not beyond help in any way, but you probably do need professional help rather than trying to wade through by yourself using websites. I needed a psychologist and a nutritionist (a certified RD), both specializing in eating disorders. I now am pretty normal looking (as I was before my ED) and do not get a puffy face or binge anymore, but it took a few years. My nutritionist told me that it takes a year of normalized eating for your metabolism to repair itself. I took about 4 because I had multiple relapses. Most ED people go up a bit above weight-restoration level and then back down again after a bit. It’s all part of the process. The healing really does happen.
I’m not sure where you live, but if it’s in a big city there should be some eating disorder centers which would be a good place to start (if you live in NYC I can make some recommendations). You need to get to the root of why you starved yourself to begin with (as a coping mechanism for some emotional stress probably) and get a good eating program that you can stick with so you don’t have to count calories, which is WAY too stressful during recovery. In fact, I was instructed to not count calories or measure. An RD can help you with some meal plans that do not require any counting, and the counselor can help with all the issues that go along with the recovery.
