I want to compare her to the sky.
A metaphor is saying something IS. For example. Instead of saying: My mom is like a diamond say My mom IS a diamond
Take your mothers personality and compare it to something that reminds you of that personality.
my mother is the sky always visible but never within reach......jk dont put that for your mom.
My mom is my sky, always around never hard to be found.
my mother is my sky my earth and my moon? hows that?
