Best Monty Python voice - "I'm not quite dead yet!"
Saef, all my sympathies! Empathies, even. I've been MIA lately due to collateral damage from this very thing. Busy with resume updating, interview planning, contemplating ... and I'm still not done with it. I spent about a month in the uncomfortable spot of not knowing where I was going to land, only hearing, "don't worry - everyone will have "something"". It is difficult to face that with optimism! Massages worked best to defuse the stress for me but I confess I lapsed back to the nightly cocktail for several months and am now in the process of breaking that habit.
The update: I am expecting a job offer in less than a week from a group I worked with a long time ago. Pros - I was very good at it back then and it hasn't changed that much, it gets me away from my desk now and then (less sedentary), and it plays to many of my strengths. The department is well-organized, consistent, and takes pride in incremental improvements. Cons - will be traveling again, though this time only US and Canada. It takes work to make it intellectually stimulating. I will have a corporate cell phone again, and be "on call". It can be a high-stress environment at times, and also moments of very high visibility during a crisis.
On the other hand, I have my current position, doing much the same thing only for a different manager. Pros - it REALLY plays to what I like to do, and there will be infinite opportunities to learn new things whenever I choose. My new manager is a terrific human being and the guys I work with are tops at what they do. I had to move locations, but that puts me closer to the vehicles and the parts coming back from dealers, and I can talk with the suppliers and engineers just about any time I need to. It is also the type of work that stays at work and does not intrude on my personal time. Ever. Cons - my boss's boss is one of the most incredibly toxic people I've ever met and seems to have it in for my boss. He's one of the few people here to ever get demoted for awful leadership/people skills (10 years ago), so now he's angry and bitter on top of it. I don't need to deal with him often, but when I do it has me on edge for days. Also, the new organization (which is a regurgitation of an old organization scheme that utterly failed) has goals that conflict and at least as of now, no consistent direction. And, I shouldn't forget to mention, my workload has doubled due to my partner in crime being sent to other responsibilities.
I'm really on the fence and I probably only have days before I will be forced into making a decision.
