I can understand this very well. It's something I have struggled with too.
I learned over time that part of it was due to my perception of others. I learned that unless you really know someone it's almost impossible to interpret their expressions and language accurately.
I learned that I can only be responsible for myself, and this level of hyper vigilant observing only hurt myself.
I learned to manage my behavior to show that I am a non threatening participating team player, by showing a gentle interest in their well being in a way appropriate for work.
If I had issues with anyone or anything I wait till I know for sure that's what is happening and not my sensitivity and hyper vigilant thinking reinterpreting events
I also learned how to present myself as a nice person whose there to do the job I was hired to do regardless of what others say or do, by dressing in that way, and acting in that way.
If you don't think any of those ideas are relevant then maybe we work in very different careers, and your job is based on being edgy. In which case, I guess I don't know.
