I can't tell from your post what your therapist did and whether it was unethical or not. I know you feel she lied, and that there was a misunderstanding about confidentiality in your records.

I do hear you that you have unresolved feelings about your therapy and feel harmed and not helped by it.

If I were you, I would see the therapists supervisor and see if you can sort it out.

I can see that the new therapist telling you the old one was unethical did not improve your feeling of trust toward therapy even with the new therapist.
