baby fever

Everywhere I turn there are people who are pregnant, who have just had kids, and kids. I can't handle it any more. I'm in tears because I want to be one of the ones with a kid. I could just kick myself for giving mine up. What was I thinking. I know what I was thinking but I'm just in a real depressed mood right now. And it seems like every time I turn around someone else I know is engaged. I'm so sick of being single. I wanna settle down. Why haven't I found him yet?
