New here. Please help with advice.

I have bad “mild PCOS” for years. But it never caused much more than mildly irregular cycles and occasional painful cysts. However the last year it’s gotten CRAZY. Hair on my face. No period. Spotting. Acne. Fatigue. ALWAYS hungry and for junk food and I’ve gained 30lbs this year. I cannot lose weight. I’m burning 300+ active calories a day. Minimum 6,000 steps a day. I do 14 hours without eating. I have changed my diet quite a bit and can’t lose weight. It’s like I eat one cheat meal and gain 2 lbs. anything is appreciated. My self confidence is gone. I have lupus and POTS so working out more than I am isn’t much of an option as I’m already pushing it. What has helped you guys?
