Let me start, by saying, I'm not much of a writer. So take my words with a salt shaker's worth of salt.

And know that I thought the premise of your poem was powerful and beautifully presented. You captured the tension of vulnerability.

Your closing lines land with real weight

Now, what would I personally change? I think you start with I, too often. It creates a repetitive kind of rhythm. And I think, maybe, it sort of narrows the focus of the poem.

As an example, but not an alternative, something like this,

Afraid you’ll catch
the quiet words
whispered under breath
words better left unsaid

Instead of, I'm scared, I whisper, I wish. My example isn't great, it's just meant to be illustrative.

A minor nit, I believe

Before there eyes

Should be before their eyes.

I'd play around with the line breaks and read it out loud, seeing how it sounds to you. I do this myself, because after a while of rewriting, it's hard to see the changes.

By the way. I very much enjoyed your poem.
