Pregnancy anxiety?

So I'm 32 weeks pregnant with my first (last pregnancy ended in miscarriage) and 100% freaking out. I was going through the clothes I got from the baby shower and just seeing how tiny her little outfits are sent me into a full on panic attack. How am I supposed to take such a little person home and take care of her and keep her alive for the rest of her life?? I feel like I can't do it and I don't know how to get over this feeling.
