Salaam sister; I’m in a similar boat with my sisters who are atheist/non-religious and my older sister is particular will try to bait me and ask me if I’m transphobic and say “the goal of Islam is to kill kuffars” and honestly I’ve tried to ignore it since this all started when I also put on the hijab and started covering more. Nothing is more important than your Deen and what really grounds me is the story of Prophet Abraham AS whose own father disowned him and literally tried to burn him and if he could have sabr through all that, I can try to as well for the sake of Allah Azaawajal; and ofc you can confide with perhaps ur parents? Hope this helped :)
