It is not within the scope of this website to diagnose the causes of the symptoms mentioned. It is recommended to maintain regular remembrance of Allah (dhikr), supplication (du'a), seeking refuge in Allah, and fortifying oneself with divine protections. There is no harm in performing ruqyah (Islamic exorcism). Additionally, one should keep oneself occupied to prevent dwelling on thoughts, avoid sitting alone, and hasten to marriage as much as possible.
