Dad is being kinda mean to me I think ?

okay I have always wanted to learn to play music my friends taught me how to do a few songs on the piano and I own a guitar. But they always made me. Chose between music and a sport or they just said no . Yesterday my dad told my mom he wanted my little sister to start taking piano listens cause he read something online about it being good for a kid to play music. And I tried telling him I was upset because they won't let me and I dont play a sport anymore and lindsey plays two. And my dad said no one asked if you were upset cause no one cares. And when I asked if I could take piano he told me no and said stop being a jealous little beat your almost fifteen she is twelve get over it. What do I do?
