Going back to work

I'm going to take 6-7wks off after baby comes then start back at work ... Unfortanently I do not have the pleasure of being a stay at home this time around... I was for 6 yrs with my son and daughter but since have been divorced and have to work .. Me and my SO both work and need my income... The thought of leaving my baby and not staying home absolutely  terrified me!!! I'm so scared and dreading leaving my baby and he or she is not even here yet!!! Anyone else feeling this way??!! When I was a stay at home mom I wanted to be a working one but now that in working all I want is to stay home !!! :(
