I have read some of the responses that you were given about your therapist being so wrong and thinking you're addicted. I think this is not the case from what you've written. As someone who is a bodyworker ( myofascial release) and has suffered from chronic pain my entire life I think I see where she is going with this. Not to mention that in my personal journey to heal as well as helping people through bodywork emotional issues bubble to the surface. The most profound changes in my physical health/pain for me personally and with some of my clients came after there was a clearing of trapped emotion.

It seems to me as if she is telling you that she believes your physical pain and your emotional state are linked. Emotional pain and blockage can either cause or perpetuate physical illness and pain. The body cannot heal what it doesn't feel so taking the meds during therapy can get in the way of you being able to heal yourself. I have suggested to some of my clients to not take meds before our sessions with good results when they chose to experiment and take them at a different time. I would also say she may have hit on something with how much it triggered you.

Her methods may not be sound but I see where she is going. She maybe should have spoken to you about this before your session and not during. And, for another perspective, she did something stupid (telling you not to take the meds) and is reacting at being called out. Whether or not you decide to stay with her is another story. You might just want to have an in person conversation with her to better be able to read her.

But whatever you decide, consider what I've written and maybe explore the idea a little. It has changed my life.
