You're not having a psychotic break, you're having fatigue. That's what pushed me from canvassing for John Kerry to ignoring politics until Obama's second term. You have no one to root for, you have everyone to root against and there's no upshot to investing your energy in hating into a system you cannot change.
It's okay. been there. As I see it, you're making progress - six months ago, you were berating everyone else for being losers that think this stuff matters. At least now you're turning inwards.
There will come a time when you have someone to root for and once you're ready, it won't take much. I mean, i went door-to-door for John Fucking Kerry.
