I've had similar experiences. I felt like I was back but still somewhat disconnected, numb & empty. What helps me when this happens is to work on keeping myself grounded. It happens less frequently now as I've been dealing with it in therapy. My T always asks me how long it lasts after. And I realize I get over it quicker now. It's not who you are but a result of what's happened to you.
I'm sorry you are going through this.
