I really need help! Don't know what to do about job situation?

I am currently attending college full time and I only have about two semesters left before I graduate. Originally I went to a college out of state, but after the first year it was way too financially straining and I had to return closer to home (I pay for my own education). I have had a bunch of jobs within the last year, mainly serving/waitressing. I absolutely HATE waiting tables but its pretty much the only thing I have found that makes decent money. I am trying to move back out of my parents house again, but I just got a job at a tanning salon. I only make $7.25 an hour (plus commission on packages). With 32 hours a week, I'd still be short on cash, I could pay rent but wouldn't have enough left over for food. I thought about picking up a serving job on just the weekends or something to supplement my income but I already gave the salon my full availability. What should I do?
