For me when I start losing keys and wallet and phone while I'm trying to get out the door I know I am dissociating and I literally stop what I am doing and sit on the floor. Today I made a decision not go to a stress management class when I realized that would not be the right thing to do. I also carry a stress ball, coloring book, pens, pencils, dried lavender and rose petals, and scented lotion with me. In DBT they call that a self care kit. Sometimes I bring a stuffed animal too in my bag, or a little plastic toy. I can't afford to dissociate since I'm on bus, bike and walk, although I imagine that driving would be just as dangerous. Also having a routine helps me get through the day, like if I just keep it together until I get home. I've also found knowing I have food at home all ready to eat helps too. And of course there's protein, that's really important for staying grounded.
