For webgoji, and everyone else who is curious:
Cognitive behavioral therapy - Wikipedia, the free encyclopedia
Dialectical behavior therapy - Wikipedia, the free encyclopedia
My personal experience with CBT was an 8-week group therapy sesssion, offered by our provincial Mental Heath Association. It was free, but if you missed two sessions, you were out. They offered it twice a year.
I KNOW there are books available, and self-taught courses in utilizing it---that way, you can work through in privacy, and at your own pace.
It is not a miracle cure. However, it has come back to help me, numerous times---when 'depressed thinking' wants to take over, for example---or when I just need motivation to get through some chores. It helped me a great deal after the death of my brother, helping me feel strong enough to confront what I needed to, to assist me in moving through the grief process.
Hope this helps...
