just found out my parents can’t stand my singing and have been mocking me the whole time. should i quit?

context i’m 15 and i’ve been passionate about singing for years, but they’ve never let me get a vocal coach because it’s ’too expensive’. so i was talking to my older sister (she’s 18) and she told me that my mom and dad have been laughing at me a lot, talking about how i sound shit. i confronted them about it, and they first denied, but they they confirmed that they hated my voice. well, what do you expect, you won’t let me getting a fucking singing teacher! i was gonna try persue musical theatre or singing, but now that i know i have no support, i’m thinking of quitting completely. i’m only in my sophomore year and i choose my options at the end of the year. i was thinking of music but now i’m thinking to just do something else unrelated. because i’ve been crying since i found out and can’t even talk to them right now (i found out yesterday). this has all genuinely upset me and it feels like my dreams have been completely crushed. should i follow through and quit?
