I cope poorly.
I don't recommend it, but I'm mostly anti-social, have my own little world, and mostly stay out of the way of life. If I tried to live otherwise, I would be overwhelmed by jealousy. Being out in the world is just no fun at all, because of that, and I really can't say I know how to be not-jealous.
Throw in a little depersonalization and you've got a recipe for success... Just beware that the taste is bitter, and it fills you not.
