I have gone through stages in my life where I have been around other people @CheerBear but I always seem to get super hurt so I made a very conscious choice to not let that happen again. I spent so much time when I was young being on my own - mostly locked away in my bedroom or at my grandparents to be away from Dad and the other people in my street that had hurt me for so long. I guess I learnt at a young age that the only one that could really protect me was me.
I did have friends in my 20s that I used to do a lot with and also did a lot with the people I played sport with - but behind the scenes there was the ongoing abuse from my partner so I definitely could be in a room full of people and still feel very much alone.
The dichotomy here is that I am really good with people despite me not wanting much to do with them. I can mix with/talk to people from all walks of life and more than hold my own in a social setting when I need to - I just don't want to be in that situation anymore. My pdoc and psych both thought I was on my own because of anxiety but it is not the case - it is how I have protected myself from any more trauma - and rightly or wrongly it has worked for me.
I know that as humans we do need some form of social connections but I find that through work - and to me that is okay. I love seeing the kids achieve things and it gives me pleasure when they have those little a-ha moments. Then I come home to the peace and quiet (and safety) of my home with my fur babies - and that is enough for me.
