Help depression is setting in.

I don't know what to do anymore. I want a baby so bad, but my boyfriend doesn't. And I would be okay with that if he didn't go around talking to people telling them how much he wants a daughter. And when he sees babies he lights up and always wants to take care of them. Abs now I can't stand seeing babies or see pregnant women, I envy them so much. I just don't understand, why me?
