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 Dianetics: The Modern Science of Mental Health.
This book really helped me with myself - because it showed me that it was really possible to feel better than I did before. It showed me that with this knowledge I can regain abilties and achieve happiness, and that this is entirely depending on myself.
