PCOS= PolyCystic Ovarian Syndrome

Has anyone else here been diagnosed with PCOS? I have PCOS & hypothyroidism, I feel as though my body truly hates me & wishes for me to stay far forever. Does anyone know of any ways that actually work to lose weight? I've tried working with doctors, Endocrinologists, nutritionists, etc. Changed diet, increased exercise. Gym membership, Zumba classes, kickboxing classes, just dancin cuz i like it, running 6 flights of stairs daily, etc. Am I missing something?
