This is an issue that weighs in heavily for me. For a lot of people. Not just those with a physical illness, but also those with a mental one, too.
The article basically outlines how hard it can be (and the public idea of) living with something that isn’t visibly impacting, entirely disabling or a condition that is constantly in a state of flux, and how your entire identity as someone with a disability can come down to how people judge you based on physical appearances
I highly suggest you all go and have a read. If nothing else, it’s a very well written piece.
