There are lots of different types of psychotherapy (called here "therapy" for short). If you have tried therapy before and it has not worked, that does not mean that another type of therapy won't have more positive results for you. A change of therapists may also have positive results.
Further information about different types of therapy is available by selecting the links below, or on the left hand menu. However, this is not a definitive list or categorisation of therapies, and you may well come across something not listed here, although this does cover all the most popular forms. Further information on some of these types of therapy is also available at Psychcentral.com.
