One way to decrease anxiety is to learn about the unknown. The unknown is what increases anxiety. Only if we learn more on the subject that’s creating the anxiety, then maybe our anxiety will decrease.
The more we are running the opposite direction of our fears, the bigger our fears become. But if we face our fears enough, the fear usually dissipates.
Milton Erickson says there is very little to fear. The lack of knowledge only feeds the fears within us. Not only knowledge is helpful but also experiential learning can bring about courage to face our fears.
