My therapist briefly mentioned it in one session (I haven't been going to her very long) but she said it in association with trying to get to sleep at night. I don't really know what to do or how to do it, I read that article, but I don't know if those things will help. I need to be focusing on my schoolwork not other things. I know people say to breathe, but breathing does not help me, in fact sometimes trying to deep breathe makes me feel more anxious (I am weird, I know). The smooth stone thing might work if I had a worry stone, but I don't. Sometimes I mess with silly putty and it actually helps a little with my anxiety. To have something in your hands and be messing with it, that probably doesn't make any sense but I know what I am talking about At the same time it is hard to mess with a worry stone or silly putty and take notes and/or study at the same time. You kind of need your hands to take notes, lol.
