I also do this both in real life with people I don't even know & while watching movies or TV-I talked with my T about this a while back & he suggested it could be my long PTSD history-I just can't deal with conflict on pretty much any level so things like this make me very uncomfortable. One of the many things I'm doing to work on my anxiety issues is learning to just sit with them (which is incredibly hard) & focus on the fact someone else's situation or a fictional situation can't kill me-I breathe a lot & I probably look funny but my anxiety is coming down. Like if my husband is on the phone with Dell trying to fix a computer problem I usually hide in another room & turn on music or cover my ears so I can't hear-even the thought that something confrontational could occur is scary. Actually had that happen earlier today & for the most part I was able to sit in the same room with the phone call-was unable to focus on what I was reading but sitting & breathing did get me through it. Good luck
