What is the way to get rid of the feeling of boiling anger and the desire to backbite relatives that afflicts the questioner before her menstrual cycle, despite her having stopped backbiting for some time?

Praise be to Allah for guiding you to recognize the danger of backbiting and striving to rid yourself of it. Many women suffer from depression, distress, and physical pains during menstruation, and this is natural. What you are feeling is one of the effects of menstruation. You should be patient and seek reward from Allah, for nothing afflicts a Muslim, be it worry or sorrow, except that Allah expiates some of his sins thereby. You should occupy yourself with what benefits you, and there is no harm for a menstruating woman to read the Quran without touching the Mushaf.
