With me it depends on where I am. If I am home I just go with the flow, grab my journal and free write (write without worrying about spelling, punctuation gammer and so on just write) I also draw, crafts like clay and playdoh. If I am out and about I find someplace quiet (restroom, a tree to sit under and so on and pull out my journal. I also use music and grounding techniques like rubbing my finger on my sneaker designs because my sneakers are multi texured, touch furnature, pet my cat, taste a lemon basically I do anything that I can that involves as many of my senses as possible and remind myself that what is happening is just a memory that what I am touching, and so on in the present is what is real.
