I had my baby 2 weeks ago and I'm not excited or attached to him. And I resent that I have to stay at home all the time to feed him. Is this normal or am I sufffering postpartum depression and need to seek medical help?

I felt the same way too. I constantly was moody, question myself why I couldn't get my son to settle down, why was he screaming, am I too lousy? When he cried, I cried. Everyone was happy but me. I hated that I was stuck at home by myself while everyone else resumed life as it is. I hated that the responsibility fell on me when it was time to sleep/feed/bath/change. I had lots of resentment. It didn't helped that my ex husband wasn't helping out. Fortunately my sister was aware of this and started spending time with us. She took over mummy dutie from frequently so I could have some time to myself, watch tv shows with me, have meals with me.. Until I felt a lot better. Please surround yourself with positive vibes. Taking care of a newborn sucks a lot of energy out from you and it gets lonely easily if you are alone.
