How do you care for yourself

Some people say that when you do everything for someone they won't learn anything.

The saying cook a man a fish he eats for one day vs teach a man to fish he can find have food for each day.

I don't know how to do anything, I don't know how to drive, my parents in highschool moved me to a different state I live in the USA where I was from it was hot sunny all the time we moved somewhere that it's cold snowing have to be indoors most the time, the roads get dangerous with ice and ice rain and snow on roads.

I get nervous I don't know how to do things on my own.

I'm scared to drive a car, I'm scared to go on a flight alone and get lost miss the flight, I'm scared to travel alone figure things out on my own I feel like I can't do it! My grandmother is vacationing and she said she would give me her apartment while she is away but I have no idea New York how to take a subway or a bus or the streets it's fast thinking and I don't know where to survive or live

I'm bad at directions

My question is I'm scared of Moving from this cold state to go back to a sunny state where everything is new and I have to do everything for myself I don't know anyone

How did you guys ever move out of your parents house it seems like the most frightening thing to do
