I kinda have the same situation with u. Throughout my high school (before i was 17), i rarely got outside of my house. My parent very strict. After i finish my school, i manage to got out of that house with very little money, and no one at all. My advise to u, just do it. Use your internet to get information about new place u going to move. And with money u have, probably u can afford to rent a new place and survive a few months until u land on a job. I have experience a lot of things since i move out. It was tough and u probably get to a situation where u felt really want to give up. I tell u, years that i go through after i leave my hometown, i cry a lot more than when i was a kid.
