I'm really sorry you're in pain. I wish I could say I can understand, but I've never experienced chronic physical pain. Mental pain, yeah, I can relate to :=]
I hope and pray it gets easier for you, rather than harder and harder.
For what it's worth, I really really value having older people in my life. All my grandparents are dead. I do have a good friend who's in his 70s and I really value his company. There's something inherently respectable about being old and wise or even old and cantankerous :=]
I'm sorry, that may not have made a lot of sense and I certainly didn't mean to be offensive. Take care.
