I'm facing many of the same issues and, while trying not to become depressed about it, I'm doing fairly well with a little help. I'm working with my therapist on a plan B. Having some well laid out plans is starting to make the concept of life after my current job not a nightmare but the next step. I've made drastic changes in my life before and came out good, I'm sure you have too.

That's not to say I'm giving up or anything, I still have a long time where I'm at now but I'm starting to get a pretty good idea of what I can do next by looking at the strengths I still have.

Still sucks, can't pretend it doesn't, but lots of things suck anymore. Good luck to you.
