It SORTA happened to me. I was doing CBT with ex T. And it wasn't working that well and she was having regular peer consultation with other therapists in the clinic as well as her clinical supervisor.

We were trying and she was bending her rigid frame like occasionally allowing me hugs, reading my journals which I brought in, going overtime (billed if it was longer than a certain time).

She felt overwhelmed and inadequate not knowing how to treat my trauma as I didn't believe I had trauma and she wasn't trauma informed or trained in it.

Eventually a peer of hers (now my current T) suggested schema therapy which we felt was worth a shot. She kept saying she wasn't competent but I didn't want another therapist. I was afraid of being abandoned and wanted to stick it out. So she tried but the modality demands a lot she can't give.

Eventually she told me she was going on maternity leave and had carefully chosen which substitute therapist in the practice I would see. She chose very carefully and I decided to stay on with that therapist who is current T.

I'm really glad ex T chose current T and that they both wanted me to pick the therapist I felt was useful.
