As an exchange, or like, moving out for the very first time and going to college for all 2-3 years somewhere else?
I think no matter where you are, starting school is freaky. If you've never been away from your family before, maybe doing an exchange or study abroad for a year type thing might be an easier step... but if you're really determined to move, I do think it's doable. I think you'd definitely be sad and miss home at some point, but that's normal when moving. If you really tried, you'd probably settle in faster than you think.
