Yes, therapy has left me feeling triggered a few times. It has sent me into crisis mode. My T and I work carefully so its a less chance of that happening. One thing that really helps is that I tell my T that I am triggered and not in a good state of mind. We spend the last 10-15 minutes of a session getting me back to the present and in a good frame of mind. Most of the time it works. I hate the sessions where I leave in worse shape then when I went in. It makes me cherish the times I leave in a really good place and feel like I can take on the world.
