Am I a bad person?

My husband and I have been ttc #2 for about 5 months now with no look so far. We are firm believers that God will bless us with another little one when the time is right. However, I have had numerous friends in the last five months announce they are pregnant. (many of them not excited or not prepared for another baby) and yesterday I had a break down. I'm slowing beginning to understand how easy it is to lose faith and get angry. I'm excited for my friends as babies are always a blessing, but it is really hard not to be jealous or envious. How do you deal?
