My parents want me to be someone im not. How can i get them to accept me?

Last summer, i became extreamly depressed. With the help of my discovery of MCR, i was able to get out of that pit of utter despair, and realize that i was not being me before but who i thought everyone wanted me to be. I started to dress with darker clothes, paint my nails black, i wasent emo though. Just me. But, my parents protested. I went shopping at Hot Topic, and they made me returne a bunch of stuff because it was "Too scary." My mom is always talking about "The old Mallory" but when i tell her that wasent me, and TRY to explain how i feel, my mom tells me im just going through a fase. My dad actually has the nerve to call me an emo. MY DAD! They used to be my best friends, but now they arent even supporting me going to art school. They have always been there for me, but now i really need them. What should i do?
