Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh
In the Name of Allah, the All-Merciful, the Mercy-Giving
All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.
I have some notes on your message:
It is not proper to mistreat your parents even if they are not Muslims. You must show them respect and kindness. You must ask Allah to guide them to the straight path and try to invite them to the path of Allah wisely. You do not have to obey them in case they invite you to disbelieve in Allah or commit a sin. What you did for your mother by calling her a demon is a major sin. You must repent to Allah and ask for her forgiveness.
You do not know how life will end with your mother. She may accept Islam and be eternally destined for the heavens. You must keep making duaa for her and invite her wisely along with you father. You must give the a brilliant impression about Islam and Muslims.
A Muslim must not wish to die. Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (peace and blessings be upon him) said, “None of you should wish for death. If he is righteous, perhaps he may add to (his) good works, and if he is a sinner, possibly he may repent (in case he is given a longer life).” (Al-Bukhari)
Almighty Allah knows best.
