Is something wrong with *me*?

I found out today that another of my friends is pregnant. I'm VERY happy for them because she will be an amazing mom. But this makes nearly all of my good friends here either currently pregnant or relatively new moms. And me? I'm just not quite ready. I know it's fine that I am not pregnant, but I can't help but feel a little bit like a loser. I was the first of all of my friends to get married, but the last to have a baby. I worry that something is wrong with me because I don't want to have kids right now.

And it may sound silly, but I'm afraid of losing my friends because our interests are going to be so different now. *sigh*
