Discouraged after 16 months...

I know so many couples have been trying a lot longer than my husband and I have been, but it's been pretty discouraging. Month after month, countless negative tests, doctors telling us everything is normal...

Almost all of our friends got pregnant right away and I can't help but be jealous and full of resent. I've been reading books on how to cope and keep a positive attitude. My husband is a pastor and we are very religious and we pray everyday for a little baby and ask for forgiveness for all the jealousy and negative thoughts. I guess I just needed to vent and ask for prayers. Who knew this would be so difficult?
