I honestly have no idea if my therapists suffered trauma or not. Their history was generally not a part of my therapy. If they did, they didn’t find it something to share with me.
I did have two female therapists who did share with me extremely early on in therapy and I never went back to them. It felt inappropriate so early on, and a bit disingenuous of them to do the whole “I understand because I, too, have been through this” thing. My therapy was not about them.
I definitely wouldn’t want a therapist who was still trying to work through their own trauma. I know how difficult and unstable my own journey was; I certainly don’t want a therapist who is going through that instability trying to assist me with my own instability. Sounds like a train wreck.
My therapists eventually shared small bits of their own experience when and where it was appropriate and applicable to MY therapy. Their issues were never a focus which is, as far as I’m concern, how it should be.
