I understand how you feel, I used to feel that way too, and it's hard especially after trying again and again for years. I gave myself another chance with egg donation and that worked and now i have a DS.

Egg/Sperm/Embryo donation is not that hard or takes a lot of time - especially if you try outside Australia. I don't know if you can or want to go through with it, but if you are still hoping for a miracle maybe you should try it.

I wouldn't tell my decision to friends and family either, I wouldn't need that extra stress in my life at this time. It's already hard that you decided not to try anymore, you don't need to have them trying to change your mind. Maybe take some vacation time far away from home and not answer any calls either?
