Pandabutt you are definately not alone. i to have pcos and ungortunately i am at the point after many years of trying and failed IUI's and ivf attempts that it may just be myself and hubby which was something I never thought I would be facing.
I have days where I can't see other people's kids and babies and other days I just want to cuddle them knowing I more than likely wont gave my own. I have not been able to see my niece born last nov until a few weeks ago, I did see he when she was burn but I didn't want my brother seeing my sadness on my face so didn't go see them for a while.
These feelings are things that are hard to control but you also need up do what feels right for you at the time. It has taken me a long time to realise sometimes you have to he selfish and think of yourself first.
There are plenty if us in here in similar situations and are always happy to talk. I hope you have some success soon and get to have your much longed for baby xoxo
