From my interpretation of Alan's quote that I used to start off this thread, you do not need to work through all of the things that you have repressed during your life. It is much more important to understand why you repress, i.e. how did your repressive personality develop, and begin taking steps to become more open and allowing of your emotions. When your symptoms are flaring up it is because of something you are repressing now, not something small that you repressed 20 years ago. If there are major traumas in your past, then it may be more helpful to explore those things, but most people I know don't need to dig into every little thing.
Donnie's idea about focusing on the conscious mind first is a good path. I tend to view this as thinking in the present. There are a couple of wiki pages about this:
Living Tension Free and
Self Monitor both address this issue, along with Alan' program. TMS is fueled by our fear and anxiety, and when we are in this state of hyperarousal it is almost impossible to think psychological. Learning how to calm our nervous system and reduce this stress puts us in a much better place to begin to do this work, and to accept that our symptoms are benign.
Accepting that your symptoms are benign can be very difficult, but overtime it does happen. One step that I used and that Alan writes about is using an evidence sheet. By reminding myself of all the reasons I have TMS, and all of the inconsistencies in my symptoms helped me to gradually reduce my doubts. Everyone is going to come to accept TMS in their own way, so it can also be helpful to ask yourself what you need to believe that your symptoms are benign. This approach is fundamentally based on self-exploration, and the first step is to find out what will work for you, and how you need to format your personal approach.
