kinda scared

I keep getting these little waves of panic/ anxiety when I read posts on here about how you girls are feeling the baby move and how you can't get sleep bc the baby doesn't stop moving.
This is a weird reaction I know but I think that scares me.. I'm scared that I'll feel shocked when it first happens and that shock will disturb the baby, I'm scared that it might hurt aswell.
Does it hurt you when the baby moves or kicks? Did you experience anxiety the first time it happened?
I just feel like the whole experience is so foreign and new that these changes are going to scare me senseless.
