Where can you find Bella's Lullaby by Carter Burwell sheet music?

there isn't any real lyrics but i created some for the whole song. once upon a time i was so alone then one day suddenly i found you i looked into your eyes and saw that you were all that i dreamed of when i lie in my bed at night hold me in your arms now never let me fall down i hope that you feel the way i do about you in these times of hardship promise that you'll stay here need to know that you will never leave me by myself i know i can count on you to come and rescue me when I'm lying fallen drowning in my despair you may be a dark knight but it does not matter in my eyes you shine so bright like we are on the sun you saved me from all my fears my solitude this is why i am so in love with you I've said it once and i will say it once again i need you by my side hold me tight and don't let go hold me in your arms now never let me fall down i hope that you feel the way i do about you in these times of hardship premise that you'll stay here need to know that you will never leave me by myself i know i can count on you to come rescue me when I'm lying fallen drowning in my despair you may be a dark knight but it does not matter in my eyes you shine so bright like we are on the sun i know we will make it out of here at last out of all this black pit we must fight on once upon a time i was alone then one day suddenly i found you.
