Three years go by pretty damn quick. And you said you don't have that much risk w/r/t $$ because of your family tuition break. I'm also guessing that you're single without kids. With those factors in mind, I'd say suck it up and finish. You're still very young and can always do something else later. Just be careful not to fall into the trap of thinking you HAVE to practice law for the rest of your life because you invested three years in law school. It ain't true.
And yes, I'm a lawyer.
P.S. if you weren't bored in your Civ Pro class, I'd worry about you.
