TLIK you write that it’s not the professionals job to teach Torah. Bingo! That’s my point. They won’t be teaching the powerful self help tools in the Torah- a proper Rav can do that.
The professionals non Jewish training teaches them how to get people better in touch with themselves and focus on their own happiness (selfish approach) while with a Torah approach, you can learn how to take your situation and use it as a springboard for growth towards Hashem. The personal situation i described earlier, which had put me in such a state of agony, revisited twice more. Each time I was able to handle it better- the second time I was able to focus on making happiness a choice to serve Hashem better. And guess what? The situation cleared up and was gone which I didn’t really think would happen. The third time I focused on bitachon, and there was no real crisis. You’re not gonna get this from even a frum therapist because just like you said- his training is not in Torah ideology, and he’s not hired to teach you Torah. So you’ll have very different outcomes.
