With the amount of cleaning we all do to keep down anxiety, we should all have spotless houses
I clean but for some reason it never seems to stay that way.
For anxiety I do deep breathing. Mecanix once mentioned that he spent his first months of sobriety with his shoulders curled up - I do the same thing - uncurl and relax your shoulders, sit up straight and do deep breathing.
Someone else mentioned relaxing your mouth. That works for me too, especially combined with uncurling my shoulders and deep breathing. Also closing my eyes and relaxing my face/forehead.
Avoid caffeine. Avoid procrastination so that you don't have the added anxiety of panicking and rushing around at the last minute. Try realizing that there are some things you can't control and just "accept the things you cannot change" and ride through it.
I also like to do crossword puzzles. Helps keep my mind focused on something else.
