Mood Swings

I guess mood swings are normal during pregnancy, but man, they suck. I've been having them a lot recently, but I think it's from the complete tapering off of Prozac and the cold turkey quitting smoking. I have days when I'm deliriously happy for no reason, then times when I just sit down and cry. I can't help it!I'm frustrated in more ways than one, and sometimes I feel so lonely even though that's stupid, because I have lots of friends and family in my life who are there for me. I mean, don't get me wrong. I'm happy with this pregnancy and that I've managed to make those healthy choices and sacrafices. Just some days, I feel so empty. Not lost or anything, just empty.Anyways, maybe a good night's sleep is all I need. Hopefully I feel better in the morning, cuz right now, I feel like crap.
