avhaben:
Your attack on mental health professionals is unfortunate, and your recommendation of rabbonim or gedolim here is frightening and dangerous. You have the picture backwards.
For one, therapists are not enthused or even indifferent to OTD. It is not normal, and is not condoned by therapists. To the therapist who is a goy or not frum, the behaviors we define as OTD may not appear as abnormal. But that therapist fails to judge a client by the culture from which he comes – a grave error. Fortunately, there are many frum therapists with expertise in this parsha. You can get referrals to them via the Nefesh International organization (nefesh.org), and Relief Resources is a referral agency for the range of mental health issues that is spectacular.
Secondly, the greatest Rav or Posek may lack the competence to pasken or guide a situation in which he has no familiarity. This is not to minimize their Torah knowledge, but to recognize that there are many facts on the ground that must be known before achieving the competence and exeprtise to become a halachic authority in matters of halacha lemaaseh. Rav Shlomo Zalman Auerbach ZT”L invested many hundreds of hours studying about electricity before paskening shailos of chilul Shabbos related to chashmal. Most rabbonim do not understand kids at risk or OTD unless they invested much time with the subject. An earlier comment mentioned Rav Gluck of Areivim or Rav Zecharia Wallerstein. Both are active full time in dealing with this parsha. And there are others. But the true gadol will turn to professionals and seek their guidance, to which I am personal witness. As an earlier comment noted, you do not turn to your Rav to fix your car, nor to unplug a drain. I welcome the input from rabbonim and gedolim, but I reject guidance that has no basis of experience in the subject. This is not a swipe against Torah chas veshalom.
