For the most part, Trish, I enjoy being alone, so I'm of little help to you. I know what you mean, though, enjoying other Ppl living their lives and the children playing and laughing.
Like you, I do miss being able to jump in my car, at the drop of a hat, and go go go!

I can't *jump up* and do anything, anymore.

. I had to learn to relax and enjoy what I have and can do and to not dwell on the stuff I am unable to do.
I've had years to gear up for this, though, if I was still in my 40s, 50s or even early 60s, I would still be a bit anxious about it.
