Just do what you want and what feels right, I stayed at home while attending college (travelled back everyday, about a one hour journey), and for me, it was a bad decision, I would be much happier out and away from home living in a new area.
And your also very lucky in that in your parents will support you if you go, that should make it easier.

A new area can make everything seem nice and fresh and I would recommend it, sleep on it some more and see what you think.
