Triggers can be tough - I have a bunch that my family knows to avoid. One is Rachel Ray. "I'm here with Penny Vegemaster and she's going to talk about the 30 ways we can use bok choy for Easter"!
Kidding - a big trigger for me is people in general and I tend to be anti social too. I think it's noble that you have an empathetic side. That's something I'm not all that good at but your story helps me. I am trying to be more empathetic now that I know who I am!
