I've seen similar situations before (with some co-workers) and I was in the same path some time ago. For my friends the only thing that helped was to change careers, they started non-related business (one became a carpenter and the other one started a grocery store); having a non-mentally demanding job allowed them to heal. In my case, I changed jobs to avoid being so much stressed. It was complicated to start being productive again and every day I struggle but I is becoming better and better.
