Surprised to see so many gransnetters fretting, worrying, becoming stressed or whatever word you use. This is pure anxiety and you need to get some talking therapy to try to understand what it is in your particular case that's causing it. Life promises to be not so great, and to become smaller as time goes on if general anxiety and social anxiety take root. As a psychotherapist I will hopefully persuade those of you who do feel this way that if this is an evolving characteristic it is very likely to be down to changing identities (no longer being a work colleague, a mother of young children, a manager of other people, etc.) and the growing belief that you are somehow now incapable. Please just talk these feelings through with a counsellor/psychotherapist - your GP should be able to direct you to six free sessions with a qualified person.
But how does one account for the fact that I find so many people so boring? They all talk about themselves and there are few people you can have a good chat with. I know everything about their grandchildren, son and daughter in law and their ailments and they know little or ask nothing about me. I prefer to do my own things now as I just come otherwise thinking 'Well, that was a waste of time!'
