What is spinning to my mind?

I call that number and I wait, listen to a voice and I just... hang up the phone. I don't know what to do, if I call him, what should I say?... no idea. I desperately need to know he is safe. I've been asking myself if I would've known about his problem before, I had gone there, hadn't I?... Since a year ago I decided to have anything about him. That plan was perfect, because I didn't realize he was terribly sick. I want him to know I'm worried about him... how? calling you!.... What to say?... hello, how are you? don't die (because  someone loves you!) Take care! See you. Bye

Simple? nothing!
