Based on the specific insecurities you mentioned, I'm curious as to what led you in the direction of teaching. I would think someone with those specific insecurities would be more prone to want some type of job where the majority of their interactions are over the telephone or email.

As far as your mom..... If anything, she was probably proud of the fact that you have been able to maintain the type of employment that is difficult to maintain with the type of anxieties you have.
This isn’t to answer for Sun but to address the idea of a teacher type.
Sure in grade school you’d want a relentlessly energetic, hyper patient foundation to your teacher with variation of personality and background layered on top
But starting in middle school, you really want to broaden your teacher types- gregarious teachers can be good in general and can help the capable ones advance
But sometimes the quieter ones have keener insight into the struggling students
Obviously you’d want diversity on a number of levels, that was just an energy example
