Am I crazy for wanting another baby? I feel so guilty

So my son would have been nine months old this month but unfortunately we lost him when he was two months old, and it has been the hardest time of my entire life. He was our first and only. Am I wrong for wanting another baby so soon? I love my son more then life itself, and I feel like with another baby, maybe I won't think about him as often. I don't know. Do you mommies think I'm being selfish?
