When you've experienced abuse in therapy finding a decent and ethical Pdoc/T is kind of like walking out into your back yard and finding a Unicorn just randomly standing there. At first you kind of want to poke it with a stick, or at the very least sit and study it.
Several or so weeks later you'll probably reach the "OMG I think this new Pdoc/T might actually be the real deal" stage - at which point your brain will remind you of every bad thing that ever happened with your previous Therapist, naturally signalling the end of the world.
If you're anything like me at this point you may just find yourself internally doing something like this during session...
After a while you might end up heading in the opposite direction. No need for internalised, wide eyed paranoia, you've got this therapy thing in the bag! Say it enough times and you might even convince yourself it's true...
But of course all you're doing is putting on an act, because deep down you're still thinking this...
After a while you'll probably gradually come to realise that trust after previous therapy abuse is something that needs to be worked at, it doesn't always just happen, no matter how good your new Pdoc/T is...
Eventually, with a lot of hard work, and riding the mental rollercoaster, one day you'll wake up, go to a session, and realise "Hey, this person sitting in front of me is pretty damn awesome! And I trust them 100%'. This is the point where you really gift them your mind, because you know in your heart they're not going to damage it.
And that's a pretty damn amazing feeling!
