Your information is very spotty and the client sounds complex. Your message suggests that you are trying to learn "an approach" at the same time you treat a client you don't understand. This is not recommended. Learn hypnosis and, say, an Ericksonian approach so you are conversant in what it is about. Then learn to apply your skill with clients that don't challenge your skill level. Little by little your envelope of comfort and skill level increases and the client range you can work with does too. Second point: the therapist, not the client ought to choose the treatment. I don't go to a dentist and demand that he or she use procedue "x" - I hope that the dentist assesses the situation and the best treatment due to his or her skill and knowledge. The same is even more true in therapy when the clients are less likely to fully understand the problem well (if they did they would probably have solved it.)
