hollywood,
I think you put it beautifully. Writing your emotions makes them more real, and we spend most of our waking hours essentially trying to feel less.
I suggest that you use this dawning understanding of the difficulties in feeling/expressing in your TMS work. Since it is not easy to feel, and instead, it is easer to avoid feeling, then you have a deeper grasp of how your symptoms are generated. Knowing this ----in your bones, can go a long way for you in the TMS SEP process. You may not be able to feel and express so easily, but now have a deeper sense of the weight of what's rolling around "down there." This understanding, just like your understanding of your feelings, will deepen and support your TMS work.
