There's some great advice in this thread:

I think that a certain amount of deep journaling is a wonderful thing for just about anyone. We learn so much more about ourselves and where our reactions come from. But I do feel that a major part of TMS healing has to happen in the present. If you still feel like you are making progress with your journaling, then I say, go for it! If you are feeling like you are hitting a dead end, then maybe it is time for a change. You almost certainly haven't figured out everything about your psychology that you will eventually figure out, but if you are hitting a wall (and I don't know if you are) it might mean that you have figured out everything that you are going to be able to figure out today.
That's okay. You don't have to figure it all out to get better.
I personally believe that a great deal of what drives our "Tension" Myoneural Syndrome is simply our own tension. Rhere is a tremendous amount of value to be had in just watching where your energy goes on a day to day basis. One way to start with this is the following very simple classic exercise: get a blank piece of paper and draw a stick figure in the center. Now, around it, draw all of the sources of tension that are using your energy. Just write the words out like a spider diagram or word map. Use the insights that you have refined from journaling to understand the sources of that tension. Then, as Alan Gordon emphasizes, ask yourself what you can do to be kind to yourself. What can you do to lessen that tension? Can you forgive? Can you accept? (It may take time, of course.) Can you make changes? Can you simply accept that some of the things will unavoidably cause tension and that while that is unpleasant, you can mindfully ignore that tension or feel it in your body and let it slip away? Can you use an affirmation to reduce the tension? Can you invent techniques of your own to manage it?
Reading your initial post, I wonder if a great deal of your own tension might be coming from the very process of trying to heal! This is not uncommon, and I think that overcoming it is the idea behind Alan Gordon's two amazing essays, Breaking the Pain Cycle and A Word on Outcome Independence. This idea really jumps out at me when you write, "Getting at that which my symptoms are covering up is like clawing my way out of a deep stone well. It's just.so.hard." I can just hear the tension you are feeling.
Healing from TMS is a great deal like meditation. Once you achieve peace with not yet being where you are going, that is when you will actually get there. This may seem paradoxical, but it can be done. Just watch your tension levels, and get drawn back into the life that your symptoms always distracted you from. Settle in to it a little and just focus on living (and enjoying) the best life that you can.
