I have been up against a wall with my parts having major resistance in therapy also as of late.
Finally this week I understood for the first time what my t has been trying to explain to me.
My T explains that if we're up against parts resisting that they're probably protective parts and they're doing their job of guarding or protecting the parts who hold the trauma.
It's important to respect that, because if you force your way through it, it can cause major problems.
I know it's frustrating. It sounds like you might have parts trying to almost sabotage things. I feel like I do. Sometimes I just want to tell my t all of what's going on, but my parts won't let me get that vulnerable.
