One of my friend suffers from negative thinking regarding his realatives.
He thinks that some of the actions or statements or questions from his blood relatives are negative for him, this way he misjudges him but later realizes that he was wrong. He wants to come out of his this state of mind and wants to make good relationships with his realatives
He should put forward in his mind all the time the saying of Imam Ali A S, who asks us to always think positively about the people, and to find excuses for whatever we see.
