A therapist is someone you hire, and add to your team of care givers that meet your needs for healing. You hire all your doctors as advisors etc. Think of it as a business, your healing, and you are the CEO. You bring all your advisors to the table to help you make good decisions on which way to go, what to do, what needs to be done. Would you have any trouble firing one that wasn't helping you meet those needs?

Call the current T up, leave a message or write a letter (cancel your appointments though, first, giving them time to fill them with other patients.) Just say you really don't feel you have made progress and are going to see xx xx, and to please send the new T your records, for continuity.

It happens all the time. No one T is good for all people.
