I would say this is how I am. I understand it's just a game, not a life or death situation, but I do have my moments. Especially when Michigan blatantly throws the game away. Fumble Fest at Notre Dame 3 years ago was probably the biggest time I threw a fit.
As for not watching anymore college football games if M loses, I love college football. I try to watch as many games as possible. My problem is going out after the Michigan games, so I hardly even watch the other games.
MGoBlog is definitely the epitome of my obsessiveness. I constantly visit this page for updates from Brian, TomVH, Tim, and the MGoBoard family.
