Parents don't let me be a musician?

Ok, lets face it, most of my friends think i'm crazy but they see it in a good way. However, my parents see me as irresponsible, they think i'm allienated, and they are so wrong. They say i live in my own world, and guess what, i feel good that way, But im also awere of what suronds me, my braind is always havin new ideas. I feel the need to be alone sometimes (i need time for myself), bt its not like im anti social, i'm actualy and extrovert, im always joking, laughting and most of all having fun! I'm also an artist, wich maked people think i'm even weirder. I sing, and write my own music, because that's what makes me happy. I couldnt care less about fame or money, Im just strongly in love with music. Music its the way i have to express my emotions (i'm not realy good at it face to face). I realy wanna be a musician, but my parents dont seen to understand it. I dream about music since i was 6 years old(16 now), i tought myself how to sing, and, not to be conceited, im pretty damn good at it. Ive got so many ideas!! But my parents wont let me dedicate to music. They find me weird, because it is the only thing i think about. Why wont they support me? Its realy frustrating to me because i know they are afraid that i choose to be a musician. I study arts and they want me to be something safer like a designer, but I NEED MUSIC. I'm also trying to find a job to pay for equipment since my parents wont help me . CANT THEY SEE IM DEDICATED? WHY WONT THEY SUPPORT ME!! music its something i cant realy live without, ive tried once, but i get depressed withou it, its realy weird. I JUST NEED IT!! And i need my parents to help me and see me as an strong person who has goals defined and that just wants to be happy doing what she loves!
