As to personal hell, of course the person does not need lecture. I am myself a psychiatrist and do not speak scriptures to those who come in pain. Yes some Vedantic understanding of life, change of attitudes and thought patterns, having faith in God or whatever deity they believe in, even learning some deep breathing methods is useful. But then there is a difference between this and having an aspiration for the higher life. Remember what the Upanishads say, nayamatma balheene, the Self is not won by the weak.
Affectionately,
Alok Da
