I can't seem to find any related stories of this type of TMS. I haven't seen it describe either. It might just be my experience and description of it that is wrong. This is how I see it now. My muscles are really tense, but moments of insight and clarity has lead me to some insight on how tension is developed. I have even been in a half-meditative state where I could observe the type of thinking that directly lead to tensing: and then make it this awful thinking process obsolete whenever it occurred. Mainly its the muscle and or fascia tension that causes me to be unable to think clearly. When its at 50% intensity can almost get the math formula worked out in my head, when its at 80%, I have no clue what I'm looking at, even though I half a minute before had a complete understanding of it. Mostly I'm at about 80%. When I have almost zero percent tension in my body I will feel pain in my lower back, or ass. Or a slight pain in my neck. But the pain is not a problem for me. I can live with this pain. Even though if I obsess on it. When I have managed to observe myself and how the tension is developed, I would describe its building up something like this. I will give the process which I think is causing the tensing of my neck, face and back the name "tensive thinking", because when it is directing my thoughts it tenses some muscles in my face at the same exact time the thought appears. (This is seldom apparent to me, because in a mind-state of high tension, I cannot differentiate this thought and the appliance of tension from the tension I am experiencing.) So a thought being directed by tensive thinking, for example when it tells me to move my head, would come with the tensing of face and neck. This type of thinking feels like a correctional state, or that its there to correct my behavior in any manner. And I think it might be linked with a type of perfectionistic thought pattern I cannot seem to be able to take control over. Because I can still vaguely remember how it was to be me without the tensive thinking. And thats where I think my tensive thinking wants me to go. Only it doesn't help me to go there at all. It just makes me tense whenever it tries to make me do something. It will also kick in and tell me to all kinds of things to think about, or stop thinking about, or thoughts that aren't as good as they used to be. The tensive thinking will slowly add up the tension by increments, the increments can be big and small, but in the end they add up to massive tension that is totally mind debilitating. Right now I'm having some clarity. And I think this description is fairly accurate of how I perceive it to be working. Any insight? Thank you!
