I'm scared for my brother. He's going to the hospital
Did something happen that sent him there?
No, he's going to the hospital for no good reason.
It sounds like you're scared that something wrong with your brother. You should go visit him at the hospital, it is good to worry about your family when you think things are wrong with them and going will show him that you care.
Wtf, nobody told you to worry about him and I'm an asshole for doubting him. He would never admit it, but he's just fine.
I think that you might just be worried about him and are trying to make excuses. It is normal to worry about your sibling when they go to the hospital though.
