Pay off my title loan remaining amount.

I currently have a title loan in which I have made all of my payments to date on time. I am in good standing, but I can't get out from under the fact that I'm just paying the interest every month. My most recent paycheck from end of June was 20 hours less than I'm normally used to due to NECESSARY sick time and I want to use the money I got from that check to pay off my remaining balance on the title loan and get my title back.
