Peanuts Halloween 1963: Linus wonders if he's cracking up

Poor Linus.  It's not easy for him to have faith in the Great Pumpkin, when he gets such mixed messages from everyone else.  One moment, they seem to sympathize and encourage him, and the next, they ridicule him and make him question his own beliefs and sanity.  In the end, after another disappointment, he is nearly ready to give up on the Great Pumpkin.
