I like my own company too, it's good to 'meet' others on here who aren't hung up about having people around them all the time. I'm not saying I have never enjoyed social gatherings, of course I have, and friends, but I always like to know I can get home and have time to myself. Never enjoyed staying with people. It was OK to bunk down for the night as long as I could get up and go home the next morning, the idea of getting up, hanging about, breakfasting, making small talk, terrifies me.
It's a flipping cheek for people to write and talk about how sad it is for people to be on their own (of course I am not on my own, don't live alone, but do spend a lot of time alone, particularly since I gave up work), not everyone is the same. It is sad for some people to be alone.
I've experienced acute loneliness at times in the past, I remember and recognise the feeling though it was a long time ago. It had nothing to do with being with others, indeed when I was young there were usually people around me and I felt isolated.
