Making through a shitty day - how do you do it?

[The Sleeper]

I have managed to sort of block everything like no matter how bad a day is I just stare into space, remind myself of my complete and utter inadequacy in life, how i'm not worth anything and after like 5 minutes i'm back to my normal state which is kind of down and lethargic.

That might be the most depressing thing I've ever read.
