Therapy for depression has several major goals. One is to relieve the mental pain of depression, which distorts feeling and thinking so that sufferers cannot see beyond their current state of mind or envision feeling better. Another is to give people the mental tools to recognize and correct the kinds of distorted thinking that turn a problem into a catastrophe and lead to despair. Therapy also teaches people how to process negative emotions in constructive ways, so they have more control over their own emotional reactivity. And it helps people regain the ability to see themselves positively, the motivation to do things, and the capacity for pleasure.
