Really, really great imagery. However, in the line "I thought of myself as a mermaid," I think you should just write " I thought myself a mermaid," just because it gives a better view of the river and how much you need it.

I really loved this peom
brought back lovely memories of my own
great work truly!
keep it up:)

This poem reminds of the back of a children's book. There's a magical tone to it that makes ms think that there is something else about the cold river then what's told. But hey that's just me. Great poem, it made me think.

Thanks for the read
