I re-read my original post, and looking at it now, I feel like its a little incomplete. I'm still more unhappy about my job than anything else, but the last year has also had some other stressors that, had they not happened, my job would not be so bad. I've had some family issues (that started shortly after my father's passing) that have gotten worse. I've been working at minimizing their effect on my life, but its not something I can ever have complete control over, since I'm not the source of the problem. For several months late last year, I've had a sick pet that required a lot more care and attention than he usually does, and he's only now getting back to what passes for usual for him. And, my racing season last year was pretty much an unmitigated disaster. I took down what was a reasonably competent car for a well-proven engine swap in order to move up to a different class, and despite an attention to detail, and following a beaten path, ran into enough problems that I managed to be driving my own car at only three events, so probably a total of 25-30 minutes of competition time for more hundreds of hours of work. And its still not sorted.
But back to the job, a bit more detail on one of the negatives:
The new company set us up in an Agile environment, which to the uninitiated, means small semi-permanent teams working together, with the project possibly changing focus every few weeks. For me, instead of working with everyone in the department, I have a smaller group to work with. One member of the team gets very passive-aggressive when trying to get their way, and another has no ability to be succinct. They cannot describe a problem or ask a question without it getting into a long monolog, and they are unable to pick up on social cues that they need to wrap it up and get to the point. I could work with either (or both) of these people better when I knew I'd be working with them on a project, then quite likely working with someone else in the department on the next project. Now, I'm stuck with them every day. We're also a small enough office that we only have two teams, so getting myself reassigned while keeping my job is pretty much impossible.
However, there are some pretty significant positives I either didn't mention or glossed over. We get catered lunches three days a week, and there is fresh fruit, nuts, and granola bars available all day. The soda machine is also free, but that’s not really a bonus for me. Because of the time I have in, I get 4 weeks of paid vacation a year. This is really important to me, and I know if I start over somewhere else, I'll lose half of that, at best. The commute is 5 miles/10 minutes on suburban/rural backroads. This is huge for me, as it means I can get home relatively early, and get things done before my wife gets home. I'm a morning person, and am allowed to start at 7:30 AM, and unlike a lot of tech companies, this one doesn't really push you to work over 40 hours a week, they just want to make sure you are getting your work done. Rumor is, when we move offices this spring, they will likely be setting up a gym and a rec room. Oh, and there is talk of an IPO, and the possibility of employees getting shares on the ground floor.
Its kind of nice knowing that others are in similar situations, misery loves company and all, I guess. GPS, you especially sound eerily familiar. I know exactly what you mean about everything else getting pushed out of your mind. Its wonderful, isn't it? I guess the question I'd have for y'all, is if you knew you only needed to hang on for another 10-12 years, then could drop out into the slow life, would you stick with it? I do know that if I ditch this job, and end up making half (or less) of what I'm making now, I would likely kiss early retirement good-bye.
So, I could try to find a similar job, but it might be worse than where I am now, and I'd likely lose the perks mentioned above. I could jump to a whole other field, but I'm just not sure what. Or, I could do the bum thing, and probably end up getting killed by my wife 
I'd really like to take a couple of months off, and see if that helps clear my head, but that would mean not having a job to go back to, and in this economy, since I can't move, my choices for a new job would be limited.
Reading the posts, I think I've gathered some coping strategies, for now. I've never been in great shape, but I started exercising again in the last few weeks, mostly aerobic, but I will start in on some strength training. I have been trying (with varying degrees of success) to eliminate caffeine. My wife and I are trying to plan meals a bit better, so I can start something up when I get home, so we can at least eat a bit healthier, and save some money. I still need to work more on the eating healthier part of that. If by some miracle, I can get the Neon sorted, maybe I'll have more fun rallycrossing this year. Also, since I am expanding my scooter racing, I may see about renting or buying a van/minivan for trips, as the racing is fun, but pulling a trailer with my rallycross car is stressful enough, that any relaxation benefit I get racing is gone by the time I get home.
I will try not to make any major financial decisions for a bit, and try to figure out what I could get into. In school, I really like machining, and programming PLCs. I have a tendency to try to make multiple contingency plans for the most likely outcomes (part of the reason I'm where I am now), and like working in some isolation from others. I most assuredly do not have the salesman gene. I've thought about accounting, since its just one really big rules based system, but feel like a bit of a fool for even thinking of going back to school for another bachelor's degree, especially if I'm not sure I'd like it any better than what I'm doing now. When I was younger, I was sharp enough to count cards, but I've tried that more recently, and I just can't keep up. I may still try my hand at poker, and see if any of my analytical skills translate over.
So, for now, I will slog on, and try to take advice given regarding dealing with my situation as it is, but I need to come up with and execute on some sort of plan. I really don't want to leave the safe situation, and jump into the unknown without at least some assurance it'll be alright. I'll start reading up on careers, but if anyone has any suggestions for a new path, based on what I've mentioned of my personality and skills, please let me know. Maybe I could check some of the vocational schools, and take a class or two to see if any particular trade calls to me. I may also see if I can schedule some of that vacation time this spring, and just take off for parts unknown, for a week or so. Maybe a complete change to my routine will reveal something to me.
Sorry for rambling again. Thanks to everyone who's replied so far, though.
) He kinda nailed it.....it was pretty much what I was going to say.
