This sounds a lot like me and what I do......there's a ton of conflict every day where I work and I feel all sorts of paranoia (most of it imagined). I get indignant all the time because I believe the job is below me (perhaps my PD talking there).

Starting this year, I had a very tough time staying even when I walked through the door in the AM. I would prep in the car on the way to work (be mindful, play it cool, etc) and it would ALL go to s*** in the first 10 seconds of me walking through the door when the first conflict or challenge erupted.

So knowing this was a regular problem for me, I try to front run any episodes. I meditate, stay current with my meds, sleep, read, eat well, stay away from booze, focus on what makes me happy. In the past, I was always in *fight* mode and never really happy, no matter where I was or what I was doing.

Now, I make myself top priority and whatever it takes to make that work, that's what I do. My job takes second place in my life now.......work and career is no longer a top priority for me.
