What is the reason for a married young man's feeling of anxiety, insomnia, loss of appetite, difficulty in praying Fajr, and memorizing the Quran, and what is the treatment for that?

The questioner is advised to consult psychiatrists and legitimate Ruqyah practitioners, while also engaging in the remembrance of Allah. Among the recommended supplications for removing worry and grief is the Du'a "O Allah, I am Your servant, son of Your servant..." Regarding doubt about the evil eye, if there is a strong probability of its presence supported by clear indicators, one can request the wash of the envier. However, if it is merely a doubt or an illusion, then performing legitimate Ruqyah and supplicating to Allah is sufficient, along with taking necessary precautions and consulting doctors.
