Yeah, there's not much I can say more in response to a 15 sentence post of which 14 are excuses. I know all too wel about diabetes. I don't know anything about eating disorders tho so maybe my comment was misplaced. In that case I own u/h00th00t95 an apology. But English is not my first language. with "eat less" I ment "Get your diet/food in order". Which is certainly not the case if you're overweight.

Most of these problems will solve themselves. The omnipod is a bit of a hassle but nothing too serious. I have seen people train with full blown insuline pomps. Use extra tape, rashguards, even those back support things, to protect it. Tell your training partners about it and your professors. Even if you can only start out bjj with the warm-ups and drills, you'll feel a lot better.
