Hello! I also am having lots of work related anxiety lately. How i cope with it probably isn't the best answer, but I zone out on video games daily to take my mind off of worries. I suppose any hobby that requires concentration could work

Changing jobs might be something to consider, but the only thing that fills me with more dread than going in to work some days, is the thought of starting over in a different career. (There are other places in my field I COULD work, but...as best as I can explain while being anonymous, I'm in the best possible place in my field. I've worked the big corporate scene. It was hell on earth when I left and it's gotten exponentially worse since then. But greedy management and a bullying supervisor with a temper problem is making the "mom and pop" area not so great either)

Whew...sorry to hijack, a long winded way to say I understand that the idea of changing jobs can cause at least as much anxiety as working in a stressful one.
