Discouraged but still hopeful

Ms
I've always had terrible menstrual cycles; extreme, debilitating pain that would make it impossible to function. So I went to the OB and they do an ultrasound. They found a mass on my ovary. I was then scheduled for surgery the next week. Come to find out, I have stage 4 endometriosis. I had an endometrioma on both ovaries, both ovaries were adhered to my abdominal wall, and one of my fallopian tubes is no longer useful. I had endometrial tissue wrapped around my bladder in addition to the rest of my reproductive area. I had been wondering all of this time why I couldn't get pregnant....and now I finally know why. I haven't lost hope, still trying. I made an appt with a fertility doctor. Sometimes I can't help but feel like less of a woman though. At the age of 29, I may be useless to my man.. what good am I to him if I can't give him a child? But then I try to snap myself out of it....I won't give up...I can't give up.
