I've been there, and am still recovering from burn out and a nervous breakdown.

Corporates can be hell for me.

I used to just want to drive my car into a tree on the way to work.

I was so dead inside. Just nothing going on.

I'm working from home now. But i'm still burnt out and recovering. I have no creativity. Things that should be straightforward seem pointless and repetitive.

When I sit down at my computer I'm filled with a deep existential sadness and find it very hard to do any work at all.

I got nothing, man. Nothing - full burn out.

Chewed up by the system and spat out.
