How can one get rid of intense fear of people and theological intrusive thoughts, especially after a previous experience that led to physical and psychological symptoms, bearing in mind that there was an improvement after stopping the medication "Salipax"?

Fear, anxiety, and obsessive thoughts are from the wiles of Satan. Their cure lies in relying on Allah, seeking refuge in Him from Satan, maintaining purity, performing obligatory and supererogatory acts of worship, avoiding obsessive doubts in worship, and consistently engaging in charity, good deeds, and the prescribed dhikr (remembrance of Allah). You must forget what happened with the student in high school and refrain from speaking about it to avoid giving Satan an entry point. If the symptoms persist after acting upon what has been mentioned, it is advisable to consult psychiatrists. There is no harm in seeking help from righteous ruqah (exorcists) who adhere to the methodology of the Ahl al-Sunnah wal-Jama'ah.
