But You Look Fine to Me: Invisible Disability and Flying, by E.Amato. The author has an invisible disability. She is able to walk- for short distances on some days, and the distance between airport terminals is often more than she is capable of- or if she does walk, it drains her reserves that she may need later. She describes the “scowls, the down-the-nose stares, and the odd jealousy that comes off people like a bad scent” that she experiences when she requests a wheelchair at the airport, while visibly able to use her legs. Another clear description of both invisible disabilities, and disabilities where the level of difficulty experienced varies regularly.
