How can one overcome the intense fear and anxiety that accompany university activities such as working in laboratories and delivering presentations, which affect self-confidence and diminish reverence (khushoo'), especially after unsuccessful attempts at treatment with the Holy Quran?

What you are experiencing of fear, trembling, and other symptoms in various situations may be due to an organic illness, satanic whisperings, or something else. It is recommended to fear Allah, maintain obligatory prayers and remembrances, and frequently supplicate and seek forgiveness, as the Prophet (peace be upon him) said: "Whoever adheres to seeking forgiveness, Allah will grant him a way out of every difficulty, relief from every worry, and provide for him from where he does not expect." A Muslim must also be strong-willed and put his trust in Allah. As for your statement, "I resorted to reading the Holy Quran as I was asked, but to no avail," this should not be the case, for Allah Almighty answers supplications. We also draw attention to the fact that a girl studying in a mixed environment entails many prohibitions, and caution must be exercised regarding religion in this matter if there is an urgent need.
