I'm sorry to bother you with these stupid questions, but I really need some suggestions!
Remember when some time ago I said there was a guy who was my best friend and then all of a sudden he started hating me?

Well this guy is now at the hospital. He had a car accident last night and his conditions are really bad. I've got to know it thanks to friends of my friends, otherwise I couldn't be able to find out. I was shocked hearing this bad news. He was in the car with his sister and a friend of his sister, but thanks god they're not hurt. When I found what happened today, I've tried to go to the hospital to visit him, but his friends and his sister didn't allow me to see him, saying I'm not welcome there.

I'm really worried, and I feel guilty too, because our friendship broke, and I'd like to do something for him, but as I said, I'm not welcome. What should I do? I feel so sad now
