I find that sometimes talking to someone about what has me stressed out/angered/frothing at the maw does help, this does of course require that the persons around you *aren't* the ones your trying to feed their words in raw printer-paper format.

The other ways I deal with it are to distract myself, but I find that they don't actually *solve* the problem and thus cause them to come back with vengeance at a later time.

So my advice is simple, if you can deal with the issue do so after thinking about it for a while, if not hold back and deal with it slowly.
