What's you goal? Do you want to help a specific person or do you want to gather general knowledge. A clinical trial can tell you whether a treatment works for the average person. It however can't tell you whether it works for a specific person. When it comes to helping a specific person with a serious issue the correct solution is often about trying multiple approaches. If you try 9 things and one works you win. When it comes to therapist, it's important to have good chemistry with the therapist. If you don't fell comfortable with a certain therapist they probably won't be able to help you even if the practice a technique with has studies to back it up.

On the more personal question of what to do here to get the best treatment: You care more about your condition than any medic, and so are motivated to spend more time on it. However, a general practitioner will have much more experience than you in diagnosing and treating mental health issues in the general population, and a specialist in mental health will know more about their area specifically than you can realistically hope to. (Unless you have a very rare condition, have the background chops to be a doctor, and put in an awful lot of work - which some people do.) My guess is that you can almost certainly learn enough to be very helpful in decision-making about your condition. I wouldn't bother with the primary literature though - go for Cochrane Reviews and NICE Guidelines (here's the ones for mental health), and recent textbooks. (NICE is a UK health body that basically takes the sort of information you get from Cochrane Reviews about what works and does some clever sums to work out what makes sense to do in yielding the highest number of QALYs given a fixed budget for healthcare.) It's not always an easy ride - some clinicians have a morbid fear of patients who have 'consulted Dr Google' - and not without good reason. But if you go along seeing yourself as an informed patient trying to engage in shared decision-making, most are happy about it in my experience. (Though my experience is limited to the UK.) If they're threatened by you mentioning this sort of evidence, I'd take it as a clear sign to change (if you possibly can). It also puts you right on the sharp end of the distinction between what's true of a population and what's true for you.
