Another year no baby

Another year goes by and no baby. I feel like such a failure. We have been Trying for 4 years and nothing. How is it that other women have unwanted pregnancies and elect to have abortions and I can’t conceive? How is that fair? It makes me sick to see how God does these things. When he could easily but a life a in desired womb. I’m honestly so bitter and tired of this. I have no more hope.
