Urgent: Prevent Homelessness for a Senior

I am in urgent need of help. I need funds so that I can secure Section 8 housing, a low cost room or a shared roommate situation. I am hoping to raise enough money to pay first and last, deposit, etc. I have recently returned to LA after being out of the US for many years, and have depleted my meager savings on temporary lodging. I need to be in LA in order to sell my TV series, but I am on the brink of homelessness. I will be 74 on my next birthday, and do not want to be out on the street or shuttling between shelters. Any amount will help, and will be so appreciated.
