The word triggered was extremely difficult for me to understand. trigger constitutes something negative to me. It took a long time before I figured out "triggered" just means the reason for why I switch. Which for me is dependent on the task in front of me. So if I have to drive one of three parts will show up, or if I have to food shop ( I hate food shopping) our food shopper will show up. Certainly if I became fearful or angry those parts who deal with those feelings would show up. There are times when fear is triggered and I don't know why or anger is triggered and I don't know why. Those are the only two things where the term triggered applied. All the other switching is functional for daily life. I am now comfortable with the term triggered although I think it needs to have a broader definition so as to remove the negative connotations.
