Help Desean buy a used car

Hi my name is Desean. It's taken a lot from me to even create one of these. Where do I even begin. I've been homeless since February of 2020 after my engagement ended. I've been sleeping on couches and now live in a 300sqft studio that was supposed to only be 30 days. I'm on day 115. 

I lost my job in October of 2020. I have severe bipolar disorder and PTSD and requested time off to treat my illness. My job deemed it a pre existing condition, denied my medical leave and used the time I was gone against me to fire me. I haven't landed a single full time job since. 2 days after I lost my job, I tried taking my life. 

I have no access to internet in an economy where every company is working from home. Most of the jobs in my field are wfh. 

My mental illnesses as well as my chronic back pain keep me from working most traditional jobs. I'm hoping to raise enough money to buy a cheap car and start doing Uber eats driving. Or raise enough money to pay off my mounting medical bills. I have 12k in outstanding medical bills due to my health. 

Every dollar helps. It would go towards food, medical bills, medications and if I can afford it a car so I can actually work a job without the risk of being fired because of my health.
