Pent up anger causes High Blood Pressure. How can I get rid of anger positively?

To get rid of anger you first have to
deal effectively with the stress. Stress
is outside of you, when it becomes anger
it has gotten in. To start, get it out of your
head and down on paper.
Write down the thing that caused you to
be angry. Fold your paper over it and never
look at it again. Now write a positive statement
of the best result. Remind yourself "I can't wait
to see the good that's coming out of this".
