Need To Fix Car

My car has recently stopped working and I need the money so the mechanic can start fixing on it. Im 18years old living on my own dont have anyone to go to for help. My money is tight right just tight on bills and with my car breaking down its just making times even harder. I called out this past few days of work because i dont have any way into work. Im trying to get my car fixed as soon as possible so I can get back on my feet and get to work. A little about myself Iam a college student was kicked out by my parents at 18 and been on my own its been hard , Im trying to stay in college so  i can get my degree and become someone but this bills and car problems stressing me
