Hi Fuzzy, Sorry to hear about your struggles with therapists.
For me, it has been trial and error with therapists. I had a couple that helped a lot and were kind and respectful, and I have had several that I am glad I stopped seeing them. Like you said, trusting someone like one has to do with a therapist to get help, and not get help or they become mean is painful. It can also be difficult of when it is time to end the therapist relationship because for me after several visits, it becomes a relationship and then how to gracefully exit without hurting the therapist's feelings can be an issue for me. But if they are mean, it is time for me to say goodbye.
Best wishes in your search for a good therapist for you!
