healthy but depressed

I've heard of postpartum depression, but lately I've been having busts of awkward feelings that are in the pit of my stomach. I'm so uncomfortable, physically and mentally. I thought i was so ready to start a family, now i fell like i don't know what I'm doing. Talking to her makes me feel sick to my stomach. When she kicks and turns and i can't rest I'm angry , i don't want to be angry. The idea of holding her makes me cry from uneasiness. I'm scared, but, not of anything in particular. Will this go away?
