Very Cute and well writen :)

some are missing,
don't know where to find,
I've searched everywhere,

great metaphor, I think it represents looking to try and heal after heartbreak, you have been looking everywhere for a way to get over the heartbreak. and about some are missing, you have found ways to mend parts of the heartbreak, you've taken some steps but you want to mend all of your heart :)

well done :) Love it
