That is exactly why I don't watch such shows unless my support network of real ttime therapy and support group members (not computer because on line support groups have a rule that when in crisis contact real time help), friends and my therapist is aware that I will be watching that show. Sometimes I record the show but not watch it, then I check in with my support network about it. That way I don't sit there and end up getting blind sided with triggers beyond my present control level.

Call a friend in real time

draw
write
listen to relaxing music
blow bubbles

squish and mold play dough and clays
