This is not part of the battle, but something I wanted to tell you guys. Leo was funny to cover up pain. No one was there to confert him because no one new he was in pain.
Maybe the funniest person you know is in pain, and they use humor to cover up the pain. So now that you've read this, tell the funniest person you know that you care about them, and will try to help them. Do this as soon as possible. Do it now, in person, by phone call, text, email, anything. Do it, because I'm telling you, they will be happy to know someone is there for them.
