Am I selfish?

I have struggled with feeling sad and depressed ever since I found out my second baby is going to be a boy. It's to the point where I can barely look at social media or talk to people about my pregnancy. I'm not excited at all. And I'm kind of angry. I can't help the way I feel and I can't talk to anyone about it because I don't want them to think I'm selfish. I know that this is a small thing I am upset about and so many other people have worse to be upset about but that doesn't change the way I feel.
