[pessimizer]

I would quit my job long before anything like that happened. A psychotic break may be something that burnout could lead to, but I'm sure that that's not a minimal requirement to say you're 'having a burnout' in most people's usage.

To be honest, that's just not the way I react to stress. I'm more likely to get a bit of insomnia and be overly critical towards my coworkers.

edit:

"The term 'burnout' was coined in the 1970s by the American psychologist Herbert Freudenberger. He used it to describe the consequences of severe stress and high ideals experienced by people working in 'helping' professions. Doctors and nurses, for example, who sacrifice themselves for others, would often end up being 'burned out' – exhausted, listless, and unable to cope."
