Anthony, first of all, your girlfriend is very lucky to have a guy like you. Just telling her that you love her no matter what will make her feel a lot better. Otherwise, keep on reading about PCOS. There are a lot of good stickys on PCOS symptoms and treatments on this website, so definitely check them out. From my experience, weight loss has helped me a lot. It's really difficult to lose weight with PCOS, but it is one of the best treatment options available. It took me a year to successfully be able to lose 15 lbs and keep them off, but just losing 15lbs. has made a big difference for me.
She should definitely visit an endocrinologist and maybe a dietician to help her lose weigt (if that's an issue).
PCOS is definitely not the best experience for anyone, but you have to remember that a lot of women manage to live healthy lives with it and it should never get in the way of who we really are as individuals.
Just give this some time and I think the both of you should be fine, especially with your emotional support.
Good luck and welcome to the website
Feel free to ask anything that's on your mind, everyone here is extremely nice and helpful
