help abuse escapee purchase a vehicle

i am female, 23 years old living in the northeast without any family around. i was discarded and ejected from my home by my abusive ex that i finally found the strength to leave. now i lost my job and my car was towed due to the aftermath of the breakup. i just need to get a car that will run well enough so i can get a real job. i do odd jobs but that isn't enough to cover my $800/month in bills. please consider helping although my need is so ordinary. its life or death for me right now. ive been starving and im on the brink of losing my apartment.
