Anxiety over baby coming

I am 35 wks & suddenly fee like I am on a fast moving train that I cannot get off of. I love my baby kicking around in there, but I am starting to get anxiety about when he comes out. What if I am a terrible mother? What if I find I don't like being a mother? What if it drives my husband and I apart? I love my husband with my whole heart and do not want to lose the great marriage we have. What if I miss all the time that it's jut him and I? I'm worried that when we were panning this baby that I was just thinking about the fun-filled fantasy and not the changing of diapers at 3am on no sleep. I feel like a terrible person for thinking these things. My husband completely understands my jitters and thinks a lot of parents-to-be worry about this, so he wants me to reach out to others and see if they went/are going through this themselves.
