I am sorry you are having such a difficult time. First, I would talk to your doctor. They do say if you have been trying to become pregnant for a year with no success you need to talk to your doctor.
Second, I can completely relate and understand your pain and frustration. I was where you are at 10 years ago. I have never been able to get pregnant, even with fertility drugs. We stopped prior to going the IVF route like our doctor wanted us to do. We could not do that.
My husband and I have two wonderful children - albeit challenging with special needs - through the miracle of adoption. God called us to adopt, which is why I was never able to get pregnant. God has given us the strength to manage our kids' special needs and being an adoptive family. We couldn't get through it without Him.
I can totally relate to crying when you find out someone is pregnant. I did that - a lot. My younger brother and his wife had two pregnancies (their first they miscarried) while we were trying to become pregnant and going through the adoption journey. It was a very difficult time. I wasn't able to go to baby showers because the pain was too much to bear.
We even had a failed adoption, where the birthmother changed her mind after we had the baby for a week. We were just devastated and thought we would never have a child. It was 15 months later that we received the call that our son was born and we flew out to see him. He was 30 hours old the first time I held him.
Let me know if you need someone to talk to. I have recently started a blog that talks about my kids' special needs if you're intereseted in reading it. It is http://twospecialneedschildren.blogspot.com
