Derealization is the worst mental pain that can happen to a human. It’s the loss of the language of emotions and sensations that alienates you from the outside world, rendering your inside world meaningless and marooned. It’s like losing your ability to make sound even though you’re talking. Everything is soaked in shades of metallic grey and the air tastes like cold corrosion. It feels like the energy and emotions of others have physical weight and exerts pressure on you from all sides but you can’t take anything in so it just piles up until you feel like you’re in a deadly vortex. You’re divorced from all context and identity and yet you’re confined. It’s deeply paradoxical with no meaning at the core to differentiate.
