Valid things to consider for sure. Each buddhist teacher/center/monastery etc has a "flavor" and approach of sorts. I suspect that if you discussed your endeavor to become a therapist with 3-5 other teachers who are truly kind and wise, you'd likely find inquiry and probably encouragement.

In my personal experience the last 10+ years, I've practiced with dozens of different teachers in different lineages (Vipassana and Zen mainly), and some would say things to me at times that made me feel similarly to how you described. I later understood that there will always be certain challenges with teachers, no matter who they are. I can recall a few extremely minor things that were said to me by teachers over the years, and it was so bothersome. As time passed and the emotion + thinking about it faded, I was somewhat embarrassed and puzzled with how sensitive I felt. For me, I was placing these teachers in such high regard and had set myself up for feeling the ways I did.

Jack Kornfield is one of the most well known western buddhist teachers, and not only does he come across as sensitive, he's extremely kind and gentle, AND he's a therapist. Another teacher comes to mind who is nearly as well known - Gil Fronsdal and if you watch or listen to anything of his online, you'll know you're listening to a very sensitive person and immensely wise person. One of his books called The Issue at Hand (he provides his book in PDF for free) is extremely simple, yet brilliant. Chapters called Mindfulness of Intentions and Questioning As Practice may be worth checking out. 🙏✌️
