Very deep, and expressive.

This is a very powerful and thought-provoking poem. I love the way you've used "elephants" as a symbol—they seem to represent heavy, almost overwhelming emotions like shame, judgment, and the weight of the past. The imagery of the "crystal cage" is particularly striking, conveying a sense of both entrapment and fragile separation from the outside world. The repetition of "Through the crystal cage, I see elephants walking in the shade" creates a haunting rhythm that mirrors the sense of being trapped in these feelings. Your use of "blamed by the world" and "judging every moment" really conveys internal conflict, while the phrase "How should I touch, how should I swallow your words?" speaks to the difficulty in responding to or even processing the kindness you mention at the start. If you're open to suggestions, I might recommend exploring the contrast between the "gray kindness" and the emotions of shame and torment in a bit more depth—maybe drawing out how those contrasts interact throughout the poem. That could add a layer of complexity, but your poem is already deeply evocative and moving.
