I think you might be best served by making use of the collaborative working relationship you've developed with your existing therapist to access this type of therapy. (admittedly, I'm just an administrator of this type of service -- but not in your country).
Your current therapist, who I presume has worked through something like a functional analysis of all of your presenting, and likely, co-existing, problems, and not just your dissociation, could discuss, with reference to the Case Formulation of your sitation, the strengths and limitations of each type of therapy -- as they pertain to you specifically. Your therapist could then contact the clinical director, Rick Greenwald, at the TC at JRI -- the place which developed CBP, and provides extensive training in it -- and obtain the list of therapists in your locale who have received certification in the use of this therapy.
I certainly don't think it's "too early" -- CBP has been around a while now -- but whether or not it's suitable FOR YOU, and available NEAR YOU remain the important questions to have answered -- something best done by your existing therapist after discussion with Dr Greenwald and his staff.
Unfortunately, I think it's likely that the efficacy of this therapy is but one of the important clinical questions as to its suitability for you, due to those likely co-existing problems.
