I find this quite a difficult one, probably I think, because it is!
I can tell myself all the right things, gee myself up to go out, and feel great, but when I meet people, new or old, I can often be found to just quietly withdraw. Especially with a group of people, I find I just don't feel confident in a crowd any longer. I do find myself feeling so out of the loop, boring, nothing to talk about and so on.
I am not too bad, one on one, as I like to think I am a good listener, but in a crowd, I pull on my invisibility cloak. Don’t get me wrong, I don’t feel I am inferior as such, I just have little to say, because of this small, shrinking world I now inhabit.
It can become such a catch 22 situation, the less you do it, the less you want to do it, the less you socialise, the more difficult it is. I can’t see an answer to this for me, as my circle gets ever smaller, so do the opportunities.
