My car now needs a new head gasket.

I don’t get paid until the 1st (I own my own business as a cleaning service, my clients are fairly new and unpredictable). I honestly only have $87 to my name right now and I’m trying to hold onto that for gas until the 1st of the month. It’s tight but not the worst situation to be in. That is until my car decided to overhear and just take a crap on the freeway. Turns out if the head gasket. I don’t know much about what that is honestly but my car doesn’t work at all, and I need it to even make money. I don’t have friends or family (living). It’s just me and I honestly don’t know what else to do. I’ve aksed a few people, but I felt too guilty because I know they don’t have much either. I’ve never done this before and I’m not even sure if I’m doing right. I don’t expect anyone to help me out, but if you do, I truly thank you from the bottom of my heart.
