<human>: Over the past year, my gf has started developing health problems that she hasn't been able to remedy. They are similar to problems that her mother has suffered through her entire life, and the indication of their onset is that her problems will be the same as her mother's, and permanent. She has become depressed, miserable, and angry because she feels as though her body has betrayed her. On top of this, my life has been going extremely well. I've been excelling at my job, got a promotion, won an award...I feel as though I'm at the top of my game. The only place I feel any sadness is at home, where sadness is abundant. I feel selfish for being annoyed that my gf's ailments are getting in the way of me living the good life. I feel sad because I can't help her in any way. Even when I tell her that I support her, and I support her decisions to seek treatment, get second opinions, etc., she is still just so unhappy because of her ailments. How do you live with something like this? Is this what I have to look forward to for the rest of our lives together? What can I do?

Can you provide a brief rundown of the text in within 3 sentences?
