Nubie

Please forgive me if I am posting in the wrong section. My girlfriend and I have been together for several years. She was only recently diagnosed with PCOS. It provided a lot of relief knowing why her moods and behaviour changed so often with no apparent reason. I love her dearly and want to help her. She is having a difficult time dealing with the prospect of her symptoms worsening. Also she has a weight battle and has had one from the first day that I met her.
She is a beautiful woman and I can't express how much I want to be with her for life, yet she has a hard time believing me. I know it is an immense struggle for women to deal with this disorder, so how do I help her feel comfortable when we are intimate. Tears and uncomfortable body language give me enough of an indication that she is ashamed of how she looks. I think she is physically attractive in every way but it's her inner beauty that make me want to marry her.

It's just hard to see her suffer silently. It seems as though all I can do is stand by the sidelines. I try to encourage her by giving healthy suggestion for meals ( when she asks me ). I try to be sensitive in many ways....but it all seems to no avail!

Help please?
