Mood swings 5days post

I did not expect to be so emotional after the birth. We have been home for two days and I am constantly bursting into tears! I feel so overwhelmed and worried that I won't be a good Mom. I am sad and feel guilty about it! I should be super happy! I read that "baby blues" are normal the first 2-3 weeks. But that is not comforting! I want to enjoy her but I keep obsessing and panicking that I won't be able to take care of her and myself and the house! My Husband is off work until next friday and I am already nervous for him to go back! Anyone else have this the first week and when did it get better?
