Is it normal to be scared Sh*tless when you are moving out?

27 (almost 28) lived w/family all my life, support them a bit, Finally moving out.
Please don’t laf at me, it’s KINDA a cultural thing.
In some cultures the kids move out when they get married.
Anyways, I have issues just like everyone else, don’t wanna get into it and make you think that I want you to feel sorry for me.
But I’m finally doing it. 3 more day!!!
