I think the biggest sign is that if you feel unhappy or miserable then that's a pretty good sign that you might not be living life correctly.

those who self-esteem when given a life without them caring about his own circumstances, often make himself as if nothing for himself and others

hopefully such a person should be given a clearer Assistance as any other human being
