Having PCOS must be hard to cope with misty. I looked up recommended diets with pcos & it looks like a "normal" healthy diet is recommended. Low GI, low fat, fresh fruit & veg, fish, minimise processed food etc. If you concentrate & look at it as an opportunity to get healthy (& lose weight) instead of feeling bad about the pcos it may make it easier to cope with, especially if the side-effects reduce.
I know a few women with pcos & it does suck. It's fine to vent. This is your space. Hang in there sweetie, xoxo Cate
PS Try oat bread, which I love. I get a sour dough one. I can cope with eating that but don't eat any other bread with gluten.
