How do I deal with my alcoholic parents who are emotionally and socially abusive, increase my depression, and drive me to contemplate suicide?

This world is a place of trial, and whoever is afflicted with parents who drink alcohol must be patient and treat them kindly, even if they strive to make you associate partners with God. Accompanying them with kindness is obligatory, based on the Almighty's saying: (But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with kindness).

Your thoughts of suicide are a satanic whisper and a major sin, even more grievous than drinking alcohol. Turn to Allah with supplication for your parents' guidance at dawn. Seek out a wise family member or someone influential to advise your father. Admonish your mother and utilize her emotions to encourage her to abandon intoxicants. If your efforts fail, you can temporarily separate from them if you cannot bear the situation patiently, hoping that this might be an effective remedy for them.
