Save the truck!

I have always been a survivor. Always made do, and helped many people along the way. Unfortunately, at the ripe old age of 65, I find myself in a bind. First, No insurance, which is fairly common, but I also have congestive heart failure, and atrial fibulation, on top of severe, well earned chronic pain. I was getting along okay, but the covid-19 situation just cost me important customers and sales of violins, with no visible sight of a return of the market.
My biggest and immediate problem is my truck loan, 3,000, which was from a friend and he is in bad shape now too. I am behind and need to pay it off, as he trusted me during good times, and I cannot let him down during bad times.
All my life, I have paid forward all the help I got along the way, and hope some will come back.
Thank you for listening to my tale of woe, I know I am still very lucky, compared to many.
And of course, I am quarantined at home, and managed to get the flu, hopefully just the regular kind, as there ain't no chance I can afford to get tested.
So, there ya go in a nutshell. If you can help at all, I would be very grateful.
