Hi, Ruth. Well it sounds like even though depressed and ill, you've manage to become Internet-savvy at 77? Wow, that's terrific!
You know, most of us kick ourselves in the behind when in later years we realize that our elders held so much interesting stuff in their heads and we didn't take advantage of the time we had with them to ask things. If my Grandma were still around and Internet-savvy like you, I'd encourage her to surf the Net and find one of the places that lets you write about your life, sort of a diary site. There are lots of those sites.
I have been friends with two lady writers who began to write in their seventies. Their stories are really something, some interesting, some hilarious. I love to read their stuff about growing up. Do you write short stories?
