Is it BED?

I am 20years old now and i had no struggle with food when i lived with my family and since i moved out i started having so much problem with food and its the only thing i think about and i feel so drained and done right now. My weight was pretty normal i was 5’3 and 104lbs and i was diagnosed with PCOS, my doctor told me to do keto low carb diet and thats where my problem had started. I started new diet, healthy eating thing but now here i am lying with BED feeling miserable its like i cant even manage my relationship with food and gained more weight. I seem to have developed body dysmorphia too bcs even if i lose weight, i always feel the fat on my body and i look so big in mirror which I am really tired of. I really want to get out of this cycle and make my life not revolve around food again what should i start doing? Maybe should i stop thinking about losing weight or healthy diet thing??
