Are you immune to workplace politics by now???

It's crushing me. It's so bad I want to drop out of my postgraduate programme, and start from scratch. It will set me back by almost 7 years....but....I can't deal with workplace politics I'm too dumb to keep up with it. It's highly distressing. I should probably just suck it up and deal with it but I don't know how to pretend it's not happening.
