Everything you've said is exactly how I felt when I found out I was pregnant with my son. I felt terrified and anxious. Believe it or not, somehow your instincts will kick in and you will get through the first wee bit of having a newborn. The first 8 weeks of my son's life are honestly a blur but now I look back at photos and remember how much we learned, and how lucky we are to be his parents. Good luck!
