WHAT IS A MIND SET OF A HUMAN?

That is what you make to exercise your choice

Happiness is very difficult to feel or see while in depression but it can be felt. You have to really focus hard, and look at the simple things. Like the sunshine, kittens playing, watching children play... Being around happy people will help you feel some happiness if not fully while in depression. It can be done as despite my severe depression I can see many happy times I have had during those times.
