I think that's me, because I always wanted to be fun, social and popular and even daydreamed about it a lot when I was by myself as a kid. I would fluctuate between acting shy most of the time and acting outgoing, and people would be really taken by surprise by the latter. I was rejected a lot, and my pride as well as pragmatism led me to believe that I was simply more to the I side--oh, that, and being raised by a flagrantly E caregiver who would express an exaggerated perception of my I-ishness compared to the rather extreme E of said caregiver. That person had an extremely dominant personality, too, so in contrast I probably gained an exaggerated perception of myself as being socially inept.
I never really felt, as in
felt, social anxiety until I was an adult, though--with the exception of butterflies in the stomach due to stage fright and things like that. I was just a kid who wanted to be well-liked and found myself on the receiving end of a lot of rumors and nasty behaviors. No really visceral feeling to that, back then. But as an adult, and having been in more physically threatening situations, I have a more reactive and 6-like phobic/counter-phobic experience around people. I still wish to be loved and popular, and now I also wish I had cultivated one-on-one friendships from my younger days and kept the better ones, but I definitely spend most of my time, even in a crowd, isolating myself and avoiding. It's not just shyness and fear of being rejected and/or judged, now, although it's still partly that. Now I'm also afraid that a situation will explode and result in harm done to my life, whether to my body or my reputation or both. It's more of a fear instinct now.
Even when I try to be friendly and have a good time with others, it's not exactly an interaction. In those cases, I seem to overwhelm people with excitement, a lot like Tigger would piss people off by pouncing them with friendliness. And they don't often relate to that the same way they do to each other when they're being relaxed. Some people are entertained, and some are annoyed, but it doesn't lead to us relating to each other. It feels like a surface encounter. I'm afraid of getting scratched down to my soul and bleeding from my soul, so even when I'm friendly, there's like a bubble of exuberant friendliness around me, and it protects me from experiencing the relationship on a more intimate level.
Mostly, I keep to myself. It's always the quiet ones.
