I do find it somewhat interesting that I have never considered giving myself any options whilst I’m in a state of anxiety followed by social interaction. My fight or flight responses go numb and I feel submissive to please others. I wear my heart on my sleeve way too much, and consequently, it’s led me to be the victim of emotionally abusive relationships. And I never learn from this behaviour either.
Oh, but you did learn from your behavior. Otherwise you couldn't even articulate how you feel in those moments.
I think recognizing your ability to be self analytical is a big step in the right direction. So many people never even realize they can look at themselves critically. And if you can look at yourself critically, you can devise a strategy for anything.
My own strategy is to limit myself to 1-2 hours. That way I don't get too tired and overwhelmed. Then I can retreat knowing I have left on a good impression and look at the event without too much emotional thinking.
