What is the guidance for one who suffers from psychological depression, obsessions, illusions, and fantasies?

Question:
May Allah reward you with good and do you well. Here is a message sent by a listener who says: Ayn, Qaf, Lam, Sad, from the Eastern Region. Our brother says: I complain of psychological depression, sadness, excessive whispering between me and myself, tension, and a lack of feeling of comfort. How can I get rid of these painful phenomena? Knowing that, praise be to Allah, I read the Qur'an. Please advise us, may Allah reward you with good and do you well. Is a person held accountable for these obsessions and fantasies, and do they have an effect on his life, or are they mere illusions and fantasies with no validity? May Allah reward you with good.

Answer:
They are mere illusions and fantasies with no validity, and they are also from Shaytan to make you sad with them. So you must rely on Allah, be patient, and not be affected by these obsessions, while seeking refuge in Allah, Mighty and Majestic, from the accursed Shaytan when you feel something of that. You seek refuge in Allah from the accursed Shaytan, and you repeat that. You must also recite the Qur'an, and recite the Qur'an frequently, because that drives Shaytan away from you. You must also keep to the morning and evening remembrances; by reading Ayat al-Kursi after every prayer, you read Ayat al-Kursi, especially after Fajr and after Maghrib, and you read after it Surat al-Ikhlas and the two Mu'awwidhat, and you repeat that three times, meaning you repeat Surat al-Ikhlas and Surat Qul A'udhu bi Rabb al-Falaq, Surat three times, three times, and you supplicate with whatever types of morning and evening supplications are easy for you.
And by that, Allah, Glorified and Exalted is He, protects you from these obsessions. Because you sought refuge in Allah and turned to Allah. And Allah, Glorified and Exalted is He, protects the one who seeks His protection. There is no harm in consulting psychiatrists to see your condition. Perhaps they will find a treatment for you from beneficial medicines. For Allah has not sent down a disease except that He has sent down for it a cure. Perhaps you have some nervous tension that affects you, and the doctors have a treatment for it. Yes?
