trying to find a job and have car issue

Hello,

I was recently laid off from my job after leaving an abusive relationship. I have been applying to jobs lately and have had a couple of interviews, but have not heard anything back about getting hired. I am currently crashing on someone's couch and have only my car and the clothes I left with. My car bearing seem to be bad and i'm too afraid to drive it so i've been walking where I can or taking the bus. My funds are getting low and I have to give $500 to the person i'm staying with for rent. I googled wheel bearing replacement and for my car it looks like its going to be around $400-$500. That was my way of transport and way of getting to the food bank. Its difficult carrying those things public transport. It may possibly be my home if i can't find something soon enough to cover rent. Any bit can help. Thank you so much.
