Well I've certainly had feelings like that before, self-loathing and the generalized frustration that I'm wasting the privileged life I was born into, etc, and it's never been to the extent of mental illness, or even particularly necessitating sympathy. I think it's a pretty established, almost cliche sort of existential angst where you're trying to find your place in the world, & so on.

I mean okay he could legitimately have depression, but you'd think it would pop right up in a google search.
