Maybe you have a bad picking mechanism?
Much like the woman who constantly chooses abusive partners.
Rather------to expect all therapists to be excellent is utopian thinking so perhaps your methods for choosing a therapist are bad.
And you did choose to actively stay in a bad therapeutic relationship for two years which is quite telling. I've had bad therapists, but never have I ever wasted so much time on them.
I think you want us to tell you that it's all on them, none on you. Sorry, but I can't do that. It keeps you in perpetual victim mode and takes any/all responsibility off of you for choosing a qualified and competent practitioner.
Yes, we do have a responsibility to find the best people to treat us. Some of my doctors are quite far away because I insist on the best and don't ever settle for less.
20 rotten therapists? Yes, at a point it is indeed on you. I struggled to find a good therapist and it was hard to hear that I was adding to my own difficulties, but it was true.
How are you screening these therapists? What are you looking for in a therapist?
Also, I think you're in a state where you expect someone to save you.
This will not happen.
If you aren't willing to do the initial steps of getting away from toxic people, then therapists can't really do much to help you heal.
A therapist isn't going to do much more than tell a client that getting away from toxicity is in their best interest. Really----they can't. It's not their job to force a client to get to a safe place, and IMHO this would be counterproductive toward the end goal of self empowerment and independence.
Why do you still have toxic family in your life?
