Defective

I have been feeling really defective lately. All my life, (basically all my life, since I was twelve anyway) I have wanted nothing more than to be a mom. Since I was in my early twenties I decided I couldn't have kids. Both of my younger sisters had gotten pregnant while on birth control, and here I was not on anything and trying with my bf of 5 years and getting nowhere. I decided then I couldn't, and while I gave up trying, I still didn't go on birth control. Still to this day, with a new guy, and nothing. I recently learned I have PCOS and that just confirmed why I have had so much trouble trying. Now I just feel completely defective and sadly my SO wants a baby more than I do... And I feel worthless to him because I can't give him what he wants. I sat up and cried for two hours the other night while he tried to comfort me.... But he doesn't understand that I feel this way because that's what us women are here for. To carry the children... And I can't even do that.
