Lift won't come out here. When I say rural, I mean rural.
I understand "rural" because I live in a rural area, too. (By choice, thank God). You need friends who can help you with transportation. Focus on making some local friends. There are many useful threads here about how to go about doing that. The animal shelter is a good place to start because there will be people there who share your interest in animals and their well-being.
Meanwhile, get strong by exercising and eating right. Your injuries sound minimal and of the type that heal themselves with time. If they were serious, your family would have sought medical care for you.
At your age, it is time to build some independence in your life. No one else can do it for you. But we can encourage and cheer for you to take control of your life. Go for it!!!!
