Are the chest tightness and shortness of breath that you suffer from – despite memorizing the Qur’an, performing abundant Dhikr, and praying Qiyam al-Layl – considered to be an evil eye, envy, an organic illness, or what, and do domestic problems play a role in this, and how can a program of Ruqyah Shariah be applied?

You should perform Ruqyah (Islamic exorcism/incantation) by reciting Al-Fatiha, Ayatul-Kursi, and Al-Mu'awwidhat (Surahs Al-Falaq and An-Nas). Adhere to the supplications for distress and anxiety, especially the invocation of Yunus (peace be upon him): "There is no deity except You; exalted are You. Indeed, I have been of the wrongdoers." Increase your acts of seeking forgiveness (Istighfar) and sending blessings upon the Prophet (peace be upon him). Occupy yourself with what benefits you, and relieve yourself with some permissible recreation. Try to identify the causes of your problems and treat them, knowing that Ruqyah is beneficial in all circumstances, and what you are experiencing might be due to the evil eye or envy. It is recommended to consult a trusted doctor.
