I learned my triggers and figured out most of the anxiety I experienced was because I was forcing myself to try to do things my neurology is not set up to do (sensory processing disorder) I knew deep inside that my abilities and skills were not adequate to meet expectations of most others, and that I could not change a lot of that due to my neurology. I learned my abilities in "real time" interactions were impaired due to 25th percentile visual processing, and 35th percentile audio/hearing processing.
Once I adjusted the things I attempted to do to fit my abilities and my own skills and stopped trying to live up to the expectations of others, much of my anxiety went away.

I no longer go places where there are lots of people, loud background noises and music, nor do I "eat out" or go to bars, restaurants and other busy active noisy places.
It has reduced the sensory overload I experience. I limit my interactions with others to only a couple of compatible individuals at a time. I have learned scripts for doing grocery shopping, post office, doctors office, etc and with a long lifetime of practice, I have learned what to expect from situations that used to throw me into panic. Over my long lifetime, anxiety has got better.
