Do you know that when something happen that makes you really upset and angry and you can't just let it go? It is circulating in your head the whole day and prevents you from working and if you've managed to distract yourself for a bit it sneaks back into the front seat of your attention at the first possible moment? And you know you really have to let it go to make a rational decision about how to deal with the upsetting situation. Especially if it is work related and your emotions on in shouldn't matter - or at least they are not helpful. Oh, how I hate this! It does not happen very often, but if so it has a tight grip. Aaarrggss! I hope sleep helps my head a bit to sort this situation!
