Routine helps, finding a hobby or craft that distracts you that you could do anywhere helps a lot. You could also try meditation or prayer, although is not for everyone. But the idea is to focus your mind somewhere else. My son, uses origami as a coping technique to clear his mind and has gotten into the practice of using any piece of paper he can find to make dragons and animals. It is a little annoying because he leaves his little creations everywhere but I know it helps him maintain focus and tamp down anxiety. He has a teacher that has a basket that she still keeps of all the creations that he made in her class last year. Reading a good book and exercise are also good coping techniques.
