PCOS - I googled it and now I'm freaking out

I had 2 miscarriages in the past year and a half. This second time - back in June - I was diagnosed with polycystic ovary syndrome. The OB/GYN told me not to worry about infertility because I've been able to get pregnant and my miscarriages were a result of PCOS. However, just recently I realized I should probably look into it a little bit more, since the doc's concerns were more about the miscarriages than PCOS. So today, I looked it up and it says some symptoms may include weight gain, hair loss and leads to a higher chance of diabetes. This just breaks my heart. I recently lost 15 pounds after working out with a trainer, but after the miscarriage, I feel like I exploded. I gained 10 pounds back and feel much bigger. I also have thinning hair, which makes me even more sad because I love my hair, and now I find out why I'm losing it. My parents both have diabetes, which was one of the reasons why I started working out (which I admit I haven't done since the miscarriage) but now, I might develop diabetes by age 40 because of PCOS. I honestly don't know what to do. I feel so powerless. I'm probably overreacting, but it sucks that that could be my life. I could gain an excessive amount of weight, grow hair where I don't need it, lose the hair on my head, never have kids, develop dark spots over my body, and many other unwanted symptoms. Since there isn't much research, it's unclear on how to treat all symptoms. I'm just venting. It might not happen, but it might. I trust in God. However, it still is a tough thing to anticipate. Especially since I'm already seeing some symptoms come to life.
