anyone have knowledge on PCOS

I was diagnosed in February if this year after years of missed periods sudden weight gain and struggling with anxiety and depression . The doctor pretty much just said loose weight and go on birth control and that was that . I can help but feel like I need to find a better doctor . I work out five times a week and eat healthy and I'm not loosing weight . It took me almost a year to loose 20 lbs . Can anyone give me any advice or insight on how I can be more proactive about this condition ?
