Sample size of one, but yes, it is: Years ago I took my work stresses to bed, each and every night. Eventually I realized these stresses were feeding me to a vicious circle: Stressed in bed, sleep poorly, fail to refresh, get less done - and do stupider things, get more stressed.
Eventually I just flipped the switched and stopped it. I wish I could recall the moment (or period?) more clearly so that I could describe what I did well enough to make you believe you can do it too, but it was a long time ago, and I stopped worrying about it pretty soon thereafter.
Will those stressors be there in the morning? Is there anything you can do about them in bed? Stop worrying.
(And stop convincing yourself there is something you can do about them in bed, because you know very well that you need a fresh mind and a fresh perspective to do your best work. And you know very well you are not going to get those things worrying with your head on the pillow.)
Rituals can help, such as commutes: Leave the office stressed, put things out of your mind as you go home. Be mindful of the sky, the clouds, the people around you. Make up stories about them.
On the way in to the office, plan how you will evaluate the stressors.
And use the "will ignoring this get me fired" rule for everything. That really helps with focus.
(I still think for a living - but now I'm quarter-owner of a consulting firm - stressors now are ever so much greater, but my stress is generally less, because I segment and defer.)
