I'm sorry about what happened!
For my previous T (jungian therapist) therapies like CBT were bull.sh.it. But he was the one that traumatized me. I came to him because I had social anxiety issues and was suicidal, depressed etc...I remember in the second session he made me relive a traumatic memory, he was very pushy, and didn't respect my level of comfort. This therapy made me feel even more isolated. He never gave me positive feedback, positive words, or reassuring, when I said "I love you" he dismissed my words as if they weren't important! So I think therapy can fail more because of the therapist not the type of therapy. I think the therapist has to recognize when a client needs an instant support (for exampel the client is in a really bad place and needs a quick support) or when a client is ready to tell their story. A therapist has to read the client's non verbal cues, understand when they are in discomfort, when to push or not! Basically every therapist has to adapt to the client's needs. And if they prefers to do in depth work and can't do cbt for example, and the client needs a quick type of therapy (like cbt) then the therapist has to tell the client "I'm sorry but it seems like you will benefit more from other therapies, not mine" with honesty.
