I'm sorry that you've had to cope with all of this, Ansalathon. This
was posted in one of the other threads as an example of a letter used to explain a personal situation to health care practitioners; you could always consider corresponding with therapists in this way to ascertain whether they'd be right for you.
I've said this somewhere before (I'm not sure where), but my suggestion for a starting point for finding a therapist is to find someone certified by the American Board of Professional Psychology
(assuming you're in the US). I'm not saying that certification is enough to assure you that a therapist is right for you, or will not contribute to the problems you already have in dealing with mental health practitioners, but the requirement of professional development & continuing education means that you have a better chance of finding someone sufficiently aware of the needs of patients. Licensed practitioners are also required to post a notice in their practice giving the details of who to contact in regards to complaints about the practice of psychology (the Department of Consumer Affairs, usually). You are within your rights to ask any practitioner about the details of their license to practice, other professional certification and qualifications before you become a patient, or at any time during treatment. You can also contact your State licensing body to confirm license details.
