Well.. not sure I could call myself a rational thinker with a straight face (though I'm blessed to find myself where I do on the curve) or a philosopher (since that's a term I reserve for the Kierkegaards and Deleuzes of the world).. but I suppose there's context somewhere in which it could be stated as such.
I didn't know there was philosophical counseling to be had as treatment, but I've often wished I could have found a therapist who at least had an understanding of advanced philosophy. I suppose the idea of it actually being incorporated into a treatment methodology seemed like too much to hope for. I also don't have a clear sense of how true to the original work the practice of Lacanian psychoanalysis is, but where I live it's hard to find anyone taking new patients even with good insurance, let alone with that kind of specialty. A lot of therapy seems to be needed in these thar hills. I do have a colleague that is a philosophy professor of some renown, that I've considered asking where he turns when he finds himself in a more existential crisis, but I haven't yet been able to decide if he'd be likely to take the question personally.
In my own personal experience I've found a direct correlation between the degree to which a therapist is able to grasp broader philosophical concepts though, and the relative success of the treatment process. I think it has to do with better big-picture thinking and ultimately diagnostics; with helping to not be a hammer that sees everything as a nail.
