I had the chance to do it, had it all set up, but at the last minute my parents said I couldn't leave the country without a parent as long as i live in their house.
That made me depressed and I failed half of my classes that semester.
Now that I'm moved out, I'm trying to save up and move abroad to escape.
Anyway, if you have the chance to do it, do it. Some programs help you with money if you and your family can't save up enough.
