An other way of dealing with depression.

The "toxic mind"  Theory

http://pages.nyu.edu/~er26/depression.html

in a nutshell
depression would be the outcome of stored, stucked chemical mesengers in the
synapse of neurones and specially stored noradrenaline and adrenaline.
(repressed anger) the release of anger by redirecting it toward the primary
abusers (in your mind)  is alleviating depression by reestablishing the
flight and fight response.
