On subject, I say go for it Andrew
You're "young" enough to give it a go and if it doesn't work out still head home.
Regarding folk's comments about missing family, the world is just so much smaller a place than when thel likes of me were your age.
Whats the worst that can happen.....you dinnae like it, you come home.
If you don't try it, you could always regret not taking the chance
