They (...) call what I have an invisible illness, but I often wonder if they're really looking. Beyond the science stuff. It doesn't bleed or swell, itch or crack, but I see it, right there on my face. It's like decay, this icky green colour, as if my life were being filmed through a grey filter. I lack light, am an entire surface area that the sun can't touch.
