Man and woman who have strained married life may be well advised to consult psychiatrist also.
Because depression causes chemical imbalance in brain which may lead to suicidal thinking.
Once thinking is disturbed, they think somewhat like this.
Man: It does not Matter even if I have to die for that. But I’ll make sure that you become a widow and be condemned by Society and your relatives for emotional torture you have given.
Woman also thinks in same way. Her aim in being suicidal is to free herself from unbearable emotional pain and to ensure that husband is condemned after her suicide.
Such thoughts require earliest medical attention.
