I usually review my toolbox from my WRAP plan. One of the things in there is a list of stuff to do. If you don't have one you could google "healthy coping ideas" or "thing to do"

Some of mine...take a shower, go for a walk, read something at pc, phone a friend, suduko, puzzles, talk to my therapist or other support person, mind mapping, art therapy, read, board game, relax outside, guided relaxation, etc...
