I've seen this sort of thing before, and I'm really unsure how I feel about it, though I guess it makes me feel uncomfortable. As somebody who has suffered from depression to the extent that it has affected my ability to study and work (in quite significant ways), I can see that it is a 'disability', but I definitely wouldn't feel right "self-identifying" as disabled, and I can't help but feel there's something cynical about doing so. Of course, from my own experience mental health can have a great impact on your physical well-being too, but by the logic of privilegistas themselves, can an otherwise physically-able person who suffers from depression really speak on behalf of a person whose disability leaves them immobile?
