If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Scientology: A New Slant on Life.
This book really helped me with the feelings I had that were troubled or confused and it made me know that I was not the only one on this planet who had difficulty with unpleasant and unhappy situations.
It gave me a way out of things that didn't make sense to me, the failures that I had experienced, and the troubles that I saw around me. It gave me the ability to create life the way I wanted it to be.
