I've also had a crappy day at work and got upset with a manager but kept my cool for the most part. Although I reacted inside the same way you did an was still mad about it when I got home. I think this is part of my drinking thinking. Back in my drinking days I would have gotten plastered to be able to take it. Today I had to deal with it sober and I am still not very good at letting things not get to me. I'm working on it and your post helped me tremendously to realize that I just need to let go and not solve it with a drink.
