You are not at fault for the mixed diagnosises -

Sounds like the diagnosing was not done by having a comprehensive Psychological evaluation done.

Part of the conflicting diagnosing comes from how the mental health field changes their diagnostic criteria. Then sometimes agencies have different things according to the county and state laws for example here this state does not recognize certain disorders depending on the persons age, and some insurances wont pay for therapy for some disorders for example here for people under the age of 18 the term Schizophrenia is not recognized. Those that have the diagnostic criteria for it recieve about 5 different labels so as to cover all that is needed to maintain and treat that person with the correct treatment plan for Schizophrenia without calling it Schizophrenia.

Confusing I know but that the life of living on HMO's and so on.

To start with whatever psychologist or psychiatrist you have request a comprehensive psychological Evaluation with suplimental tests for DID. When those results come back you will know what your exact diagnosis is on the diagnostic axis I, II, III, IV and GAF.

Then no matter what therapy professional you have you will recieve the correct treatment plan

As for the actual completing therapyand having a great therapy experience well all I can say to that is a person gets out of therapy what they put into it.

Before starting therapy sit down and decide what you your problems are and some ideas of how to accomplish solving those problems and what you are willing to do and not do for therapy. This will come in handy for your first month or so of appointments. those appointments are for getting to know each other and work on setting down your therapy goals to be completed during therapy. after that its a matter of you completing those goals.

Good luck.
