What should a woman suffering from obsessive-compulsive disorder characterized by fear of Satan, persecution, and fear of confined spaces do?

It is recommended to fear Allah, observe the obligatory duties, and realize the doctrine of Tawhid (monotheism). The monotheistic believer relies on Allah and fears no one but Him. Fear of anyone other than Allah originates from Satan and his whisperings. If you feel fear, remember Allah's name, repeat the word of Tawhid, and recite the prescribed supplications and remembrances. Dedicate time to the Book of Allah, reciting and reflecting upon it. You may also consult the counseling department, a female psychiatrist, or a trustworthy female practitioner of ruqyah shariyyah (Islamic exorcism/healing).
