Help us get a ball joint so we don't die

Our van has a broken ball joint, so we can't really go anywhere. We just spent all the money we had on fixing our overheating problem. I am a type 1 diabetic and have doctor's appointments I have to make it to in order to get my insulin and supplies, without them I will die. Quite literally ANYTHING will help. This really is a life or death situation. If you can, please help
