foot amputation struggles: Urgent Housing Aid

I was recently released from the hospital after having part of my foot amputated due to infection in the bone from my diabetes. I haven’t been able to work and I’m living in my truck. I found a camper for rent, but it needs a decent amount of work before it’s livable, and I just don’t have the funds because I can’t work. My disability claim was denied. I am appealing it. I’m not one to ask for help like this, but I am absolutely stuck. I can’t properly take care of my foot living out of my truck. If you feel it in your heart to help in any way, anything is greatly appreciated.
