Overall on this forum, I have noticed a trend. It is either of a PTSD sufferer debating switching therapists, or posting a question, and others suggesting the individual should consider a new therapist. One of the key features in PTSD is AVOIDANCE. Yes, you're uncomfortable. But if we keep running from things that make us uncomfortable, then we are simply perpetuating our symptoms and thusly, our PTSD. I hate it break it, but therapy isn't going to be a wonderful walk in the park, and if it's not, the only thing standing in your way is the therapist you're walking with. No. Sorry. It doesn't work that way. It's going to get ugly. Real ugly. But what's important it the therapist we have ISN'T going to walk away and leave us drowning on our own. They will be there through the ugly, the good, and the maybe okay times. I'm a bit of a hypocrite writing this post, but I'm working on it myself.
It's great that you feel in control with one therapist, but with the other....unless something is entirely detrimental to your well-being and she communicates to you that she cannot meet your needs, I would say stick with the one who is supporting you while stuff is coming up for you. Yes, we have a huge say in what we want to work on, but it is highly unlikely we are going to pick looking in places where we've stashed our trauma - otherwise we wouldn't be attending therapy in the first place!
Hope that makes sense. It was a little bit of a talk to myself too, so please don't read too much into it if it comes off harshly. My only goal is to share alternative perspectives :)
