Psychotherapy deals with complex feelings.  Some people are unable to cope; they may have intense urges: Self harm, Compulsions, Panic Attacks, Addictions. These issues can have a profound impact on their life.  Complex deep-seated problems such as these can sometimes require a longer process because this intense level of anxiety may have developed over a long period of time.  There will be a greater number of sessions to allow the person to relieve these emotions and feelings, enabling them to cope with their life.  Most people will require twice weekly sessions, however in the case of those who are unable to cope at all, it could require more.
