How can I break free of all this?

I am an artist. I write, draw, sculpt, sing, play instruments, etc. I love expressing my creativity. But I feel like I'm ALWAYS censoring myself. Always. If I write a love song, I shamefully hide it somewhere and often rip it up days later out of sheer embarrassment. I can't play my music too loud or I feel embarrassed. I never draw or create anything "unacceptable" or "wrong", because I feel as though my parents will disapprove. I know they'd probably support me in anything I do, but the slight chance that they won't or that I'll be made fun of eliminates any possibilities. I feel as though I'm binding up my creativity and making it "acceptable". I want to break free so badly. I want to be an artist who creates with limitless passion. Please help, how can I begin to uncensor myself and break free?
