I know that feeling LC.
I spent 32 years with my employer and in 2009 was abruptly shown the door. I was aware that the odds of staying with them weren't good, and most people employed by them knew we were living on borrowed time. It sounds to me like at least you're leaving your job on your own terms which is better than what I went through.
I didn't know what I was going to do either. But I eventually sorted things out, and got the job I have today. Not that my job is anything special, because it's not. It's a low stress, no-brainer type of gig that doesn't pay very well, but that's what I want. I tell people I'm "semi-retired" and that's an accurate statement. I like the troops I work with/around, and we have a lot of fun playing the lottery. (I'm known as "The Lottery Guy" because I run the various office lottery pools.)
My three children are grown too. My youngest just graduated from college in May. She's home for another month and then off to Grad School. The other two have careers and live in New York City. So it's my wife and I here at home most of the time. My wife cant quite retire yet as she's in her late 50's, but as soon as she reaches 62 and can get Soc. Security we're both going to fully retire. Until that time I'll do my part time job thing and play the lottery for some fun and excitement.
You folks might remember that I was down in North Carolina last March. There was a reason why we went and it wasn't just to go on a vacation. My wife's job took her down there and I went along for the ride. While we were down there we did a fair amount of looking around trying to figure out if we'd like living in the Raleigh/Durham area. We decided that we'd like it, although we went to the east coast of North Carolina too and we liked that as well.
So hang in there LC, it'll all work out and half the fun is seeing what's going to happen next. G5
