The problem is when people are fooling around and using mental health to cover up their laziness and right now there are many smart talkers who love to words dance around mental health issue to make them free from responsibilities... they keep getting better at this.
those people somehow become bad stereotype on mental health issue
It is different when a friend tells you "I am depressed, I got no job" . This person is not depressed, it is just using the wrong word. Sadness is a normal feeling for everyone when we feel disappointment.
mental health problems are over-focused feelings. People are so focused on that bad feeling that it becomes a disease.
