What is the treatment for nocturnal fear and anxiety about diseases, the loss of a sense of purpose in life, fantasies leading to a rapid heartbeat, and fear when traveling or moving from home?

We advise the questioner to consult a trustworthy psychiatrist or to contact the consultation department at Islamweb, while continuing to avoid forbidden acts and maintaining the regular adhkar (remembrances) for morning and evening, after prayers, and before sleep, which can be found in "Hisn al-Muslim."
