I do not have PCOS but I am on Metformin for type 2 diabetes. When I first went on it I lost 25 lbs really fast, but now my body is used to the medication and I can easily gain weight if I'm not careful. I don't know if that is the same when you have PCOS.
Lauren, please discuss your sadness with your doctor. Maybe there is a med you can take that will brighten your outlook. You should not lose your boyfriend over a medical problem. You should be with someone who will help you cope. But he may choose to leave because you aren't doing anything to improve things.
Good luck to you with this!
