How can I cope with this?

My fiance of three months broke it off for someone more attractive. I know I've never been one of those girls you write home to mom about. before him I was always very shy about everything and once I met him I felt let he took the weight of the world off my shoulders. I actually felt like I could be beautiful, like I could be loved. Thursday I had surgery and had both ovaries and tubes taken out so I'll never be able to have kids. I'm emotionally distraught.I think that was one of the reasons he broke it off. I don't know what to do anymore. I'll never be able to be beautiful and I know I'll never find another guy like him. I mean come on would you even think about dating me, 5'10 160lbs cynical psycho vegan. I just want to curl up in a ball and go to sleep and never wake up again. what can I do?
