Hormones are crazy. I'm on baby number two and they arent as bad this time. I think Tiff is right...surround yourself with the awesome things aboit becoming a mom..decorating...clothes (thrift stores have great stuff too!) And plan how your going tk be the best mom. Research different parenting strategies and start nesting :) it'll all be worth it...
Take your mind off of it, go for a drive, think about your baby, start your registry, go walk through a few baby clothing stores, start planning on how you're going to feed your baby, choose the furniture you want for baby, look at some maternity pictures for yourself, look at newborn pictures to decide how you want yours to be (if you're getting any)... there's tons of things to do. I went through it myself. Hope this helps...
