If you’re still interested to try and meet people, I would suggest still trying to meet up or go to locations with a bunch of people and check yourself.
How do you feel there, what do you notice, what makes you feel tired?
Very often you’ll find yourself overly alert, overly self concious, or simply not used to the experience. These all drain energy.
Try again and notice if it changes. Keep trying.
Awareness is only one part of mindfulness, you already got that, which is great.
The other part is equanimity, being aware of things, but not reacting or judging.
Doing it frequently definitely helps with hyper-vigilance and being overly aware of things.
