So recently I was treating someone in chronic pain and I was spouting facts about what happened when you detox (detox reactions). I admit I was rambling, because I've said it often. But this person visibly tensed up. I could tell they were upset, but I couldn't tell why they were upset.
Finally they looked up and said that they needed me to be more positive for them, because it was so hard not to sink into a depression. It's so hard not to let the negative thoughts win.
