I've found the following:
1. The phone calls stop after about 9 months, then they just trickle.
2. You get an opportunity to mentally detox. This is not possible unless you quit drinking the koolaid.
3. You know you're going to leave, and guess what? They do too. Your plumage changes color and they'll start to peck
at you until you leave or your plumage changes back again.
4. You get to leave without them taking any more of your time than they already took. Stop putting any more money in that slot machine.
5. Join a non-religious social group of some kind so as to stay in touch with humanity. I always liked giving talks, so I joined Tooasmasters. It's geeky, but it doesn't look bad on your resume and a lot of different kinds of professional people are there.
One year later and the wounds scab over and you're moving on.
