Welcome to pc Judi (nice name btw)
I'm sorry, that sounds very hard. I have no wise words but want to send hugs. There is also a section on pc specifically for ''seniors'' (55 plus) which I think is quite active. There is also a ''games'' forum on pc which can be good for distraction, some good people post there

I think it's possible for almost anyone to make friends online, as you have no glaring personality traits I think you too can make friends online. It's not the same as in ''real'' life, but as you have discovered, some people in real life can be flaky (as can people everywhere)...but there are some kind, thoughtful, people around too.
