I'm sorry you are feeling so down. I hope it all passes for you quickly. Maybe have hubby take a day off of work every once in a while to help you through the day. Also, it might make you remember why you liked having the day to yourself so much. *teehee*
Hang in there it will get better.
ps if it gets any worse, talk to your doc and see if you are having any PPD. those hormones do nasty nasty things to us momma's
