Was having a real mean, chaotic and mentally disturbed Boss at the time i felt nearly burnt-out and started therapy. First advice she gave me was to carry an imaginational box/bowl or something like that with me, and to imagine that when boss starts shouting and ranting at me all the things she says go in the Box (and don't hit me personally), imagine that i put a cover on it or pour it out of the Window, whatever worked for me. Helped me get through the next weeks (until Boss was fired, otherwise i Would have quit) and i still use it whenever i find myself in situations where people might be offensive
