It may be time to try therapy. It sounds like mentally, dieting is not smart for you. You may need to think of making small chances (80/20 rule- 80% healthy diet, 20% your favorite foods). You can't restrict with PCOS. Our emotions are already crazy and when you're an emotional eater, denying yourself that comfort is not helpful mentally (because we're already not completely on stable ground). All that to say: There's a reason that one of the symptoms of PCOS is mental health issues such as depression and anxiety. Sometimes, working on that, means you don't focus on your weight. So, figure out why you comfort eat; where does it come from; what else can give you a similar feeling...and then, if you feel like you're in a good place and you have some other things you can do to feel good about yourself and life in general, maybe starting then. Or doing therapy for weight loss/management. You just need to find the right person. Also, just so you know, therapy doesn't have to be expensive, you may be able to find someone who takes your insurance and then it's just a copay (everyone always thinks therapy is expensive but that's just not true. And if you have medicaid, it's free).
