Shy, everyone has rage problems with this game, but you apologized and you rarely go overboard. As long as you're working on it and you know when you've raged too hard, it's not a big deal. I get just as furious, but in the end I think it's much better to deal with loss rather than avoid it. Just keep playing and show everyone you're strong enough to be a gracious loser. It's easy for someone who's not invested in something to be a good loser, and harder for people like us, but that just means we have to try harder; you can also be more proud of yourself knowing you can accept loss even when the stakes are high.
