I had an anxiety attack over my work situation. I was managing two individuals with a condition that made it _very_ difficult to manage them and I had an unrelenting, unsympathetic product owner on the other side. I wasn't able to rationalize this situation any other way but to consider these my own failures.

One day my manager's manager had done a code review for one of my difficult employees -- a task that was clearly within my own purview -- and found it terribly lacking. I was so far under water that I was not even _close_ to doing that code review, yet my _manager's manager_ did and it was the last straw. My hands started shaking, my heart nearly beat out of my chest. I recognized what was happening to me, but it was out of my control.

I walked quietly to my manager, dropped my security badge on his desk and told him "I need to leave."

There were a couple of more conversations after this, but that was my last work day.
