Back to freaking out

Today I went to a breastfeeding class. Yes, me, at a breastfeeding class. Never believing I would actually BE a Mom, this is truly freaking me out.  I found myself overwhelmed all over again.  The nurse kept talking about how it shouldn't hurt to breastfeed (it's all about proper latching behavior and proper positioning) but the stories of what could happen and what might hurt....ouch. And then there's the dreaded pump. Really?  Sounds like most mothers have them and use them, particularly if they want to keep breast feeding while they are working. But really?! Do I have to?  And the last thing that freaked me out is the upcoming tiredness and lack of sleep when feeding a newborn every 2-3 hrs for the first several weeks. My husband is helpful, but really....How is the housework ever going to get done?  How will our two energetic dogs get enoug exercise?  And all this in the middle of winter.  Will I ever get out of the house? I'm worried I'll be so concerned about "leaking" in public etc etc that I won't want to venture out til this child is weaned! Wow. So much to think about and anticipate.
