First, I want to offer condolences--bad timing to say the least so near Christmas. Bummer. Hope you can make it through, financially and otherwise. Hang in there!
Second, what the heck do you, personally, want to do with your life? Have you thought about moving your IT skills from a blue-collar mindset to doing something for a company whose mission and purpose you really support? Are you passionate about anything? Boy, it sure sounds like you have *something* hidden away in the back of that mind that we haven't seen yet. That's what I would encourage you to go find--not just a replacement but a real opportunity. There's got to be a point at which you say "my life-mission is more than building software for the highest bidder". Find that passion and exploit it! :)
Good luck!
