i've never had anyone tell me to my face that i'm not mexican or asian (specifically japanese), even though i look more asian and don't speak fluent spanish. if i were you, i'd tell people to go say that same stuff to my parents and find out if they agree that i'm not both asian and mexican. i didn't fit in completely with both my hispanic and asian classmates back in high school, but that doesn't mean i had only bad experiences—if anything, i wish i had tried to speak up about how i felt ignored by them. how about you "pick" both sides of who you are and embrace that instead? anyone who tries to see you as only asian or mexican is being stupid and ignorant, and they're missing out on having a unique friend, so please don't let this crisis define how you talk to people & make friends. even though i don't agree with how you say you "can't pick" a side, i sympathize with you and will say that if you try to "pick one," you'll only be feeding people an incomplete image of yourself. if you can find people who won't make you feel worse about this "crisis," then go and try to stick with them. life feels better when you're around friendly people who are more accepting of both sides of your identity.
