A previous T, ten years ago, suggested exercise, and walking in the forest and throwing pine cones at trees. That had two results: first, I discovered that exercise makes negative emotions multiply and grow stronger for me, and second, I realised that that T was not particularly attuned to me. (I was never able to be very honest with her, so it wasn't her fault - I told her what I thought she wanted to hear.)

Current T hasn't suggested anything in particular, other than putting words to the emotions and telling him about them. I write a lot, and he thinks that's a good idea, but it was not his suggestion to do so. I have a life-long habit of not acknowledging negative emotions, so he's had his work cut out to make me actually feel things and talk about them. What I've traditionally done to get rid of unwanted feelings is to deny that I have them, but it's not working out so well for me these days.
