Weight loss

Does anyone have any tips for a girl trying her damn hardest to loose weight with this disease? I’ve spoken to dietitian’s, doctors and therapists. Nothing is working, no one is helping. They all tell me the same thing which is the obvious; calorie deficit and exercise. I’m doing no more than a 1200 to 1400 calorie range and I’m exercising daily. I’ve been turned down for any sort of medication that can help as well. I’m ✨frustrated✨ as it feels like no one understands.
