Tortured Passion

My passion is music,and it' forever my dream, But I cannot follow it, because I'm scared I might scream. My mind say it's unrealistic, and I would never suffice, But when was I ever asking its advice? So now I continue doing something I don't completely hate, Chemistry, BIO, and studying till its late. But I often find myself, trying to beg and plea, Asking myself, "Why can't you just let me do me!"
