People who suspect they have a chemical imbalance that causes behavioral issues should seek help from a qualified MD or DO who can prescribe the proper treatment for that physical illness.
Therapists – be careful. Some use all kinds of strange techniques that can damage sholom bayis, or kibud av voem etc. The worst will tell you to fry out, but that was more two or three generations ago when the koifer Sigmund Fraud’s dubious ideas held more sway.
I suspect there are rabbonim who can do just as much for you as a therapist. The difference is that they may not have time to give you the same attention as someone gives you when you are paying $150 an hour.
The best solution if you really feel you need a professional may be someone like one of the Twerskys (one is definitely named R’ Ben-Zion and the other may be R’ Mordechai) in Brooklyn who is both a rov and a therapist.
