Congratulations, for when you start to feel good about things. xo

I don't think it's bad to feel a little shellshocked, it's going to be a huge change to your life, one full of many emotions from frustration, inadequacy and boredom through to delight, joy, huge amusement, tenderness, awe and bursting-with-pride.
It's a crazy roller coaster, and in my opinion, the best roller coasters are the ones where you have a few moments where you think you're actually not going to make it out.

And to be honest, I remember feeling a bit numb at first too, and mine were planned. You're not sure what to expect, and you can't see a belly or feel any movement so there doesn't seem to be anything to connect or bond with and it all feels a bit surreal. Give it some time, you'll get there, and don't worry in the meantime.
