The only thing I'll say is, if you think you're too old..., you're not. If you make a change in jobs, you will still have everything you had when you quit the last one, just a new address to report to work. Every change I've made has been a step up, not a step back. My last job change occurred at 62!
I wish I had some really great advice Mike, but everything that I could say has already been said. You're in my thoughts and prayers, and I know you'll make the best of the situation.
It's who you are.
