My brother (25m) is getting married on the day of my (26f) med school graduation and everyone expects me to ditch my graduation for his wedding. I don’t want to, but I know if I don’t my relationship with my entire family will suffer.

Brother and I love each other very much. But he is the only boy, the baby, and the golden child of the family and so I'm used to kinda standing in his shade. But I've worked my ass off in med school and I would really like to attend my own graduation, but when I expressed that to my family (brother included), everyone got very upset for even considering attending my graduation in lieu of his wedding. And now I really don't know what to do..
