I'm chronically ill. It's a disability. It is. It's a crippling disability. 
It hurts. Every day. One day more, one day less. Yeah, if I'm lucky, it doesn't hurt for three days. But when I think it's gone, it fkares up again. 
Whatever I do about it, it's still there. It still hurts. It'll never go away. 
But people can't see it.
They can't grasp it.
They can't feel it.
