Help A Grandmother Keep Her Grandson Safe

My family has suffered a great deal over the last 3 years. In 2023, I was a victim of aggrevated assault by an Uber passenger. Uber does not care about their drivers or customers. I've not been able to work full time since the assault. I have sole custody of my 3 year old grandson, his mother abandoned him at 4 months old and his father passed away last year in June. We are about to be evicted and my income is not enough to qualify for another rental. My grandson is supposed to start school in 2 days and I can't even buy his supplies. It's extremely difficult for me to even ask for help, especially with my ptsd. Everything feels like a disaster...I feel defeated already and have a difficult time hearing "no" so I barely leave my home. I have exhausted all traditional sources of assistance in the county but my situation is unusual and I've been unable to find any assistance. I have run of of money because my rent is 150% of my income. If I don't get help, we will be on the street in 10 days.
