Peace of mind
There are some people who think too much about anything. Someone will think he was hurt, someone will think he was hurt by himself. If someone else shared his personal troubles with him, he would also think about it.
This extra thought robs them of peace of mind. Takes away the night's sleep. To be good takes away. They cannot easily accept everything. If these people get hurt more than someone very close to them, then there is no point.
In this way, one day or another, they become mentally ill. But treatment of this disease is very difficult. It is almost impossible to recover from this disease. It is good to think but excessive thinking is never good. Absolutely.

Prophet of Islam Muhammad says: "I seek refuge in Allah from unnecessary knowledge". In other words, the more unnecessary information you put in your mind, the lower your mental health will be.
