How can I deal with my irreligious family, given my suffering from their condition which affects my psyche, and their rejection of advice?

My advice to the questioner is to remain steadfast in obedience to Allah the Almighty, adhere to the religion, and strive to learn the rulings of the religion by listening to appropriate lectures, reading beneficial books, attending study circles, and frequently supplicating to Allah the Almighty for guidance and steadfastness for herself and her relatives, and to keep company with the righteous.
