Am I selfish?

I'm 34 and am so ready to have a baby. I no longer find joy in other peoples pregnancy. I now turn down being a God parent, after all I have 1 girl and 3 boys. Does it make me selfish, at times I fill bad other times I don't give two flying f*cks. I haven't been to a baby shower in 6 months. I'm just tried of others having what I want.
