I know what you mean about the emotional stress, loneliness, etc.
I had 2 miscarriages before a 5-year infertility period. With traditional chinese medicine & technology, finally got pregnant in 2008 & now with a 2.5 yo girl. The years of trying to conceive was very painful time for me. Especially when I see pregnant ladies walking around...would look with envy...The pain was so deep that I took a 6-month break from my job cos I just can't resolve the issue within me that God gives the gift of children to "everyone" except me. It was a mild form of depression. But thank God I gradually rise above it.
So take courage! You are not alone.
