you can not "overplay" mental illness.  it's real, can be devastating, it often alienates people so the ill person is left perhaps in a delusional tate to stew by themselves.   all mental illnesses are not the same or equal.  how many people take a "mood elevator"?    this world is stressful - it's fast, it's "coded", it's hardhearted , uncaring  and overwhelming to some.  i don't think we've adapted to it yet.  some do much better - the young keep up an confused about the ever changing technology.  WWAY way back in the day , the big concern was get food,  find shelter, make fire, find mate  and stay alive .
