Anxiety and Depression
The mood disorders of anxiety and depression, I find, are the primary reasons why people enter therapy. Anxiety is more common. Firstly, a therapeutic relationship based on trust helps the client to tell his story of how bad his mood is and how it affects him.
I tend to use CBT mostly with mood disorders. I find helping the client to see the faulty beliefs they have about themselves and their situation helps them to understand why they feel as they do. Developing new thinking patterns facilitates the client to have a new perspective about their problem and to develop skills to overcome it.
