Infertility and depression

Julia
My husband and I have been trying to get pregnant since May 2014 and I am getting so depressed. I haven't ovulated since November, my doctor doesn't know why and I can't afford infertility treatment right now. I feel broken and incredibly sad that I can't have the one thing I've wanted my entire life-- to have a child and be a mother. 
How have others coped with the overwhelming pain of infertility?
