I have pcos and I need so much help with my weight problem

Hailey
I have pcos and I have a huge weight problem and I always have. Throughout my life I've always had a problem managing my weight. At the age of 16 I was in the best shape of my life and at a weight that I loved and could live with but a couple years later after I graduated highschool I gained 87 lbs (YES 87lbs!) in a year. I never changed the way I eat what I eat or even how active I am. I'm a very busy woman between a full time job and college and I want to lose at least 50 lbs but I don't know how to! I need help from my fellow pcos ladies! I want to lose the weight to hopefully lower mybmi enough so I can have a better chance of getting pregnant within the next two to three years! Please help!
