Need to vent!

I can't really talk about this much anywhere else because people just say I'm complaining or that I don't appreciate my pregnancy. I absolutely love my baby and also definitely want her to go full term. My son was a preemie so I know the "I wish I could have carried him full term" feeling. I realize that we are all going through similar things and that is why I wanted to post on here and not elsewhere. I also have another child and realize I won't be getting any sleep after the baby is born either. Anyway the venting!

I am so tired of not ever getting any sleep. I feel like I'm going off the rails. Some nights I just lay there worried about my baby for hours. On nights I fall right asleep, I wake up constantly! The usual reasons include leg cramps, having to pee, half of my body falling asleep, or my two year old deciding he just really needs a glass of milk. I feel like this lack of sleep is not good for me or the baby! I wish I could just get one good night of sleep and I would feel so much better!
