Only once.

I had my H drop me off at a session after spending the night in the emergency room with a kidney stone. I arrived on Vicodin and was still in pain. I know that she was upset that I showed in the first place in that state. However, she decided to try to take advantage of my mental state and pain. Knowing that the Gestalt empty chair technique triggers me to panic, she asked me what would I say to her empty chair if she just decided to get up and leave because I wasn't talking to her. I reacted very calmly and said that I would say nothing to her empty chair because I see no point in talking to a chair.

Not the reaction she was looking for.

T admitted later that she was very frustrated with me for showing up in pain and drugged. She said she hated to see me in that state because there was nothing she could do about my pain. She also admitted that she was frustrated with me because I was trying to skirt around my issues for several sessions prior to this. So, she made the poor decision to take advantage of it. She apologized. Honestly, in hindsight, I would have been frustrated with my behavior at the time also.
