Dear Irrational Half of Squirrel's Brain,
Please try to remember that during previous work-related stress flares you promised yourself you wouldn't ever let work get to you in such a way that it negatively affects your health. I feel that you are currently breaking that promise and your stress levels are rising.
Because however much you don't like your new manager's harsh style and however much you're upset that the person you fancy on your team is leaving, these problems aren't really the end of the world and probably not worth the amount of negative energy you're throwing at them.
Also try to remember that as crappy as work is just now, it would be a hell of a lot crappier if you stress yourself right into a flare.
So, please, breathe. Relax. Tomorrow, go into work and let the bad atmosphere wash over you and concentrate on the really important things in your life - your health, your family and friends.
