It's good to hear that your life has improved so much - it's always inspiring to know that it is possible to change and get better.

About your question: you are aware of the fact that "evidence based" and "empirical" does not mean that those methods will work with all people, right? I definitely agree with you that methods have to have some basis in scientific thought, but that's true for most of the major psychotherapy modes or schools. Nobody denies that both relational, behavioural, and psychodynamic modalities have a solid foundation in research and have been clinically proven to be effective, although most major research studies seem to indicate very strongly that the modality matters less than the rapport between therapist and client.

If you are looking for changes in behavioural patterns, I suspect that one of the behavioural modalities, CBT or DBT (the latter being a specialised form of the former, if I understand it correctly) is probably most useful for you.
