PCOS, “Obese”, with eating disorder

I’m 5’2, 20, pushing 200LBS with PCOS and an eating disorder. I’ve been diagnosed with PCOS since I was 14 years old. I’ve always struggled with my weight and these past few years I have really let myself go. I’ve become in a depressed stage in life where I am not happy with myself and I want to change it. I don’t live on my own, so it’s kind of hard to diet but I really would love any tips anyone might have on how they lost weight on PCOS. I would love to get down to 130LBS but even getting down 10 LBS might make me feel better and encourage me to continue this journey.
