I have had plenty of days like that. Lately I have been controlling it somehow so the world does not end when stuff like happens, but every once in awhile I self destruct but the last time I self destructed I realized something at the end of the day. What I realized was holding onto that moment for the rest of the day does absolutly nothing but screw up the rest of your day, so when I have a moment of weakness all I do is make a mental note of what not to do next time or what to do and then carry on like it didnt happen. takes training your brain....
