I feel like giving up

After my laparoscopy we discovered I only have one ovary and tube working and that I also have endometriosis along with my pcos. I've tried to be strong and positive. I've also been very open about my struggle to conceive baby 2 because I know that someone out there can be helped through my pain. I am just getting tired. It's painful every month having a cycle (multiple cysts plus endo pain) and I am starting to lose faith that another baby is God's will for my hubby and me. I'm not bitter about it all, just tired.
