This all sounds so familiar to be. I go though the same thing.

Take a day for yourself if you need to, although I to find myself at the computer where I might as well have gone into the office anyway...

I usually feel better in the long run if I do force myself to get up, get clean, and go to work. Plan a day off ahead of time, and even more importantly plan to spend it with someone or doing something well away from the game.

I'm battling this whole 'sitting on hands, being nice, not being mean' thing myself. Most people know me and understand me or at least recognize I'm not being mean, just that I care or that I'm so occupied with other things I'm just not taking the time to try and sugar coat everything for them. Other people just see the behavior as smug or derisive. So I'm working on it...

It sucks because weeks of really good work that I've earned respect for gets jaded by one three line email that someone 'took' the wrong way.

Hang in there
