my dentist is a trigger. i ran into him at a fundraiser and i was a mess for over a week afterward. i couldn't come out of it. i finally called the dental office and asked if i could see him. figured he triggered it, it was his job to fix it. he spent over half an hour talking to me, everything from exposure therapy to getting a new dentist. it worked. the episode went away. i now prepare to see him at that particular fundraiser. we made a joke out of it last year.
