Gave Up

I finally just completely gave up on being a mother. Now depression is setting in bad, I have so much resentment built up because everyone around me is pregnant and having babies. I don't know how to cope. And no matter how hard I try, I can't force myself to be happy for any of them. I just avoid everyone now. Including my nieces and nephews. Especially since my brothers want to use me as a free babysitter because I don't have kids and they want to have fun. I just can't do it anymore. All I want to do is cry all day everyday.
