How do I find out if the property I got hurt on has homeowners insurance? Also, can I sue the people that caused me to break my neck?

I was standing at the end of walkway that was built to meet their back trailer steps. There was not a rail at the end of the walkway on the side of steps where I fell off of. The female came out of her trailer and that door hit me in the back, causing me to flip off her porch and coming 1 cm from being orthopedically decapitated. I was dragged inside the trailer. For four hours I know that they took my clothes and shoes off to wash them. A shirt was put on me that didn’t cover my privates. I can’t remember what they did to me for those four hours. I was then dragged and put in her car and carried home and put in my bed by her boyfriend and left a hour or so later for dead? I didn’t die, but from the moment I hit her ground after I was knocked off her porch, I was paralyzed from the neck down. They did not call an ambulance. Do I have any kind of case?
