Why I mentioned that the jealousy is a disease and get well soon because jealousy makes people so underestimated themselves by themselves, it may destroy the ability of what it gets from the world and its effectiveness. The severe virus of jealousy eliminates social function and interpersonal relationships with people. I have many case studies about teenagers to adults about to grow doubt, and it occurs not a great situation in their career life when people complain about other people when people think that he has less money and fame than others. When people do not appreciate what they have; and how they invest the talent, knowledge, money, relationship, and other faculties of life, then they suffer from severe jealousy or envy. Jealousy comes from suffering insecurity of emotions about anything he gets from life. Jealousy comes into life than they compare with others, which feels low. Distrust is the leading cause of jealousy. Sometimes it may cause somebody’s harm and destruction or self-destruction. So the solution to the disease of jealousy is to be content, humble, and appreciate thyself and also people. Understanding is the standard solution of doubt we have.
