Urgent help to repair car and get off the streets

I am going to give this a try. I am needing to raise money for a mobile mechanic to get my car fixed, it’s got a massive oil leak to the point that I can only drive a few miles and then it’s out of oil. The only place for me to live right now is this car. I was in a program for homeless persons with HIV but the funding got cut unexpectedly and it forced me right back to the street. I am also waiting on a referral from my doctor so I can get surgery to repair a hernia that I have. I’ve got to get this car running and or get into a cheap hotel I can’t handle this heat and the the temps are only going to get higher, my poor dog is miserable and I cannot risk her having a heat stroke. Please help if you can even if it’s a few dollars thank you in advance and I will keep things updated as they progress.
