Anger

This is possibly the 5th post with the message of how angry I am. This is a different anger though. I am at a point of not understanding. I am in a place where nothing makes since. 4 babies in less than 2 years. Actually it's 4 in 18 months. I want some answers. 

I have not lived a perfect life no one has. I have made really big mistakes. But my sister no she has lived her life for God for as long as I can remember. She's not perfect but she is someone that I strive to be like. She is the example of a Christian woman. And a wonderful mother. She deserves to be able to raise her baby girl. It's not fair.
