Be ready to excuse yourself to cool down on monday and tuesday or to talk to a friend (in private, of course). You're responding emotionally to work situations, which is fine, as long as you engage your internal editor. And never fear, it'll pass. You're back to calm and collected by wednesday, and your expertise and interpersonal skills are very much in demand. Block out time for your own projects while you're helping everyone else with theirs. This weekend, the sheer volume of details involved could be overwhelming, so give yourself a break and come back to it later.
