My answer to most areas of stress and distress over the last few years has been to write about it -
privately. I have found it a wonderful way to get things off my chest, like talking to a shrink (or so I imagine), but without the new stress of paying for it.
From significant ones (...not saying, but there's been a few...) to minor ones - like arguments on forums (never here of course
, you know the joke: I can't go to bed now, someone's wrong on the Internet!). Instead of continuing the argument online and in public I write exactly what I want to write, as much as I want to write, but I never send it. It sits in a folder of miscellaneous rantings and consumes my frustrations for me ... well, enough that I find I can sleep better.
ETA: Such writings are not always a direct response to the original irritation, sometimes they're a more emotive response or simply where the whole thing has led me - which is often quite wide of where it started.
