I used a large range of techniques during my recovery, not exactly the same as this, but they were all based on helping me to re focus on my physical and emotional self and the physical world around me.This was my idea -- I took a pen and colored in a section of a paper about the size of my fingertip, pressed my index finger against the spot and stamped my fingerprints on the page, and labeled next to the fingerprints "me lol."
Keep going and good luck with your recovery.
