If being suicidal is merely a consequence of one having insufficient coping resources in face of negativity, then I guess work depression can be viewed as an analogue to suicide.
The path to suicide is often one with narrowing view where the victim loses visibility of light ahead. Everything seems to be crumbling down, building impenetrable walls which dampens the victim's will to escape from the deadly quicksand.
As for work depression, it is often linked to incompetent colleagues, unreasonable superior, unscrupulous employer and demotivating environment; all of which cripples us to the extent of becoming a stupid useless idiot. What could be worst? A contract or a bond that states that even if the shit has hit the fan, repeatedly, you still have to work for them.
Just like me.
But this game of life is about who can play the game better, who can survive longer. People who can create coping resources for themselves to nullify the hardships are those who are going to be celebrated in life. They are the hopeful ones. They wait for their turn and grab hold of golden opportunities. They never give up.
Do you want to be the last man standing?
Yes I do.
So I won't give a crap about stupidity, incompetence, foolishness and hypocrisy. It's all part of the job specification. I'd say, do what the Romans do, but always be prepared to fight in any World War. Don't be a part of the hopelessness. Be the best stealth assassin. Level up and hide, and resurface only when necessary. Don't exhaust yourself but grab the gold and runaway.
For all we know, it is only a matter of 2 more years before we can glue the letter with our saliva and slam it on the table and say 'I quit!'. Even if I still don't know what I'd want to do by then. :)
