I'm terrified to have my baby.

I'm due 25th Jan and with the days to go quickly ticking over I find myself terrified to become a mother. I love my baby more than anything. I just don't think I realise yet how much he's actually going to change my life just yet. I kinda just want him to stay in there. Am I the only one feeling like this? I constantly see people wanting their babiws out early and so excited for their babies arrival but I feel terrible because I'm scared.
