Hello bunnifoo: The Skeezyks has never actually received a diagnosis from any of the mental health professionals he's seen over the years... even after having been hospitalized twice. Perhaps there's something written down in some file somewhere. But no one has ever shared it with me. Plus, each mental health professional I've seen has suggested something different in terms of what might be going on with me.
Sometimes I feel as if I've missed out on something. But then, at other times, I think perhaps it is just as well. One thing is does for me, here on PC, is to free me to go anywhere I want to reply to Threads because who knows what my diagnosis would be? I don't.

Oh... & by the way I'm now in my mid 60's!

So, at least from my perspective, age doesn't necessarily make a difference...
