Depends. If you're a minor, you kind of have to stay.
If you're not and can get there, find a job, get a place to stay, etc. and you don't feel guilty about leaving a woman who may not have much time left, then go.
EDIT: On second thought, you never said if this friend loves you back. If you're going to make such a big change, I'd suggest you do it for someone willing to commit. I mean, you could go and get rejected right off the bat or even wind up going, getting together, and then getting dumped and there you'd be.
