Is it possible for a jinn to make a person think about things and feel sad, even if he has moved past them? And should a psychiatrist be consulted in this situation?

Our advice to you is to continue performing ruqyah on yourself with beneficial incantations such as Al-Fatiha and Ayat Al-Kursi, and to frequently supplicate and recite Surat Al-Baqarah to expel Satan from the house. You can also consult a psychiatrist, as this is among the means that Islamic law has commanded us to take, and it does not contradict belief in divine decree.
