Car Service Cost

My name is Bronte and I am a student working 3 jobs and studying full time at university. I recently spent my savings on buying a new car, as my old car was dead, but yesterday, my car broke down and I was quoted $3000 to fix it. I have some savings (around $500), but not a lot as I am currently paying rent and supporting myself without the assistance of my family. Without a car I can't make it to any of my jobs to make more money. I have sold a lot of my belongings to make up for this, but I have nothing left to sell and I am feeling very desperate and need help. Any donation will be appreciated immensely.
