Dream!♥

Hello, I am a fourteen year old girl living in Alabama, USA.
Before I could write, I was writing. I would ask my mom to write for me, as I would tell her the words to my elaborate stories. I also made up my own songs and sang them. They were pretty good for a three year old.
When I was about seven, I really started writing lyrics. I never showed anyone any of them. No one knows I write songs.
At nine or ten, I took about a year of guitar lessons but quit to take dance. Now I am teaching myself guitar, piano, and voice and will start lessons soon.
My parents know I can write good stories and essays.
How can I tell them I like to write music?
My dream is to be a singer/songwriter.
My favorites are Michael Jackson, Elvis Presley, Taylor Swift, Lady GaGa, Prince, and The Beatles to name a few. Mostly MJ, I am in love with him!
Hahaha ANYWAYS. How can I tell my parents? Or anyone for that matter? I am really shy and write like a song a day, but just lyrics. I want to learn. I want people to know. HELP PLEASE!
