I had a very similar anger rise up the moment the Bills lost. I walked to the sink, washed some dishes and it was gone. It turns out as men we don't know how to handle disappointment. Regret on the other hand is useful, it allows us to think through what we did wrong so we can change it and act differently in the future. But disappointment is different, because by definition there's nothing we could have controlled to make the outcome different. So if you think about it, there's nothing useful to hanging on to anger or ruminating about disappointment because there is nothing you can do about it... Also, you are not defined by the Bills. Your worth and value is not dependent on their success in any way. You have the same inherent value as a human being as anyone else, so there's no reason to question life or ruin vacations if your disappointed by the Bills.
