Number of things here. 1) If you have partner and kid(s), give up for a decade and try again. Sounds like you don't. 2) Each job has different requirements. Find one not so mentally taxing. As others mentioned, a new job gets easier after six months as you get comfortable. 3) Eliminate the commute. Once had a job with 90 mins of heavy traffic in the morning. That lasted less than a week. Instead rented a studio about a mile from work and strolled into work each morning refreshed instead of angry. It wasn't cheap but I was able to be happy again.
