How to Not Take Things Personally in Interpersonal Communication?

I think the first thing is trying to understanding that everything isn’t about you. Your coworker could be going through personal things and could have a lot on her mind.. it could be family, their health etc you never know… I think you should just take a minute and take a deep breath. Let them have their space. Since you know you haven’t done anything control that and keep saying to yourself that they just need a personal moment.

I feel that there might not be much to do but wait. If you know you didn't do anything wrong, then you haven't done anything wrong. They are probably just having a bad day. Stress balls help, just try to keep yourself occupied, it will pass!
