I also go to the psychologist once every two weeks, I tried to avoid this but I realized that I can't do it without any help sometimes.
Also focusing more on the now then on future outcomes and past regrets has been a very effective way to reduce stress.
Stress comes also from having a huge todo list. Get psychologically stressing things done asap (ie giving someone bad news) to keep overall anxiety down and help focus on the now.
I accomplish something similar by commuting on foot, though.
* Eating right
* Having company of great friends around.
* Reading some philosophy books, once in a while.
