gender disappointment

I'm suffering with severe gender disappointment. I have wanted a girl all my life and now I'm having a second boy. I was okay with my first son, I got over it, but this time I can't. I get angry or upset every time I see girls clothes or that someone else is having a girl, and I get mad at myself for failing to have a girl. My mum is disappointed too because now she is going to have 5 grandsons and no granddaughters.
