What is the reason for a young man in his twenties feeling depression, sadness, fear, and anxiety, in addition to strange delusions, shivers, dizziness, and chest pain, which began three years ago?

The cure for worry and sorrow lies in seeking refuge with Allah Almighty and supplicating to Him, and in frequently remembering Allah and reciting the Qur'an with contemplation, for it is a healing for what is in the breasts. Allah Almighty said: "And We send down from the Qur'an that which is a healing and a mercy to those who believe." (17:82) It has also been authentically reported from the Prophet, peace and blessings be upon him, a supplication that removes worry and sorrow: "O Allah, I am Your slave, the son of Your slave, and the son of Your female slave..." And if one continues to experience what he feels, there is no harm in presenting himself to someone trustworthy in their religion who knows the lawful ruqyah, while being extremely cautious of charlatans and imposters.
