Only revert in a non-muslim family

Assalamu alaikum, im 23F and i reverted just this January this year.

so im the only daughter and eldest child of our family and im gonna be graduating in college soon Alhamdulillah. My family are Roman Catholics and i mean like both sides, maternal and paternal families are all Catholics. im the only revert and there are complications and stuff but nothing that would need excessive attention because my father’s side of the family are religious people and they’re devoted but not the kind that would pressure to just follow Catholicism, my mother’s side is a bit on a not-so religiously inclined side but they still pray and stuff.

the issue here is for graduation, i plan on wearing hijab and have been preparing for it and to whatever halal dress i can find to wear. my mother found out abt it and then she threatened me that she’s not gonna attend my graduation if im gonna wear a hijab, she also said that i dont respect them, and i should find muslim guardians to attend with me. my father has no input abt the matter yet because he’s working far from home and only comes homes every weekends so ig we’ll have a family discussion abt this on saturday, but i just feel frustrated abt her reaction ig?

fyi, they know about my reversion and ive worn hijab in family events and when im going out of the house, i had an immersion as a last requirement for my program and during the whole immersion i was wearing hijab and it was also during Ramadan, where i fasted and prayed as well and actually tried to complete it because it’s also my first Ramadan. They know about it. both sides of the family knows abt my reversion, but for some reasons, they just go on w the narrative that i might be talking to a muslim man thats why im going thru all this.

ps. my mother’s side werent brought up catholics, they all converted to catholics when they got married. So i think they’re viewing me the same way?? That im being like this because im talking to a muslim man and ill be marrying the said muslim man. I mean InshaAllah but faith is not a fruit of marriage and definitely cannot be forced into anyone.

i learned abt islam 3 years ago and have been continuously learning and reading abt it, and i can say that it aligns with me and this is where my faith to Allah swt get stronger and better and Alhamdulillah it has brought me peace within myself SO MUCHHH. i just dont know how to handle this blackmailing, maybe she’s having a hard time accepting it, that’s understandable, but i dont think that warrants an ultimatum? Idk i just feel so torn but im rlly tight on wearing a hijab

please give me advice. thankk youu, May Allah swt bless all of you with prosperity and happiness!!
