I hope I don't crack

Sometimes I think I am losing my mind- I know how I should feel but I I feel the exact opposite. I swear there are more people pregnant than not right now. At school last semester there were no less than 5 pregnant women and of all the blogs I follow there were 5 or 6 (I lost count) in the last month that have announced that they were pregnant. I want so badly to be pregnant- to have a child of my own but I feel like God is not willing to give me that precious gift.  I am not good enough. I feel like a broken record and no one wants to hear me cry about it, or worry about it anymore. Who wants to be around someone who is permanently depressed? So I am going to fake it until I make it or I crack up, which ever happens first.
