The speaker is angry and hurt, and finally says so out loud. Someone has told them they're "too old to be comforted," and the speaker points out the hypocrisy: the people saying this never offered comfort themselves. Their emotions spill over as they answer, "You made me like this."
The central image is of a body turning into metal. The speaker's face is "tungsten," hard and unreadable, while the heart is "alloy," which suggests something toughened but still made of mixed, living feeling. Rusty joints and dented bones show the damage that has built up over time. The speaker admits they may seem like a robot, yet insists they are still human.
The mood is raw and defensive, but also a little sad. The short, repeated lines near the end ("To me of all people / How dare you") feel like someone whose patience has run out. Underneath the anger is a wish to be seen and understood.
