Don't want to move, how do I stay here?

I'm a 17 year old high school graduate.
I'm living in Arizona and I LOVE it here. My boyfriend is here, all my friends are here, and I can't stand California.
I'm supposed to be moving in a few weeks to San Diego, and I DON'T want to go.
I have a job and a car, and I want to go to college here.
But my family is moving there and I'm not allowed to stay, and I'm under 18.
What do I have to do to stay here?

I'm turning 18 in November, my boyfriend is 21, turning 22 in October<3
