Ah this is great! I love the idea of a person being a deep ocean and the flow and rhyme of your sonnet felt smooth and read really well :-)

Just a small query though ...
"where them could have just breathed ..."
Did you mean 'they'?

A lovely read. I've been trying to write my first sonnet and I'm failing miserably so I really appreciate how tricky this is! Good stuff! :-)
