I'm always tense. My shoulders, neck and back are always very, very tense. I clench my jaw tightly, both awake and asleep. I'm very stiff because of how tense my body is and how tensely I hold myself. I never know I'm doing it unless I concentrate hard on how I'm holding my body. When I do make myself relax, it's instant relief - but I tense up again almost instantly out of habit and sheer anxiety. I ache everywhere because of how tense I am. :(
Just remembered... Other things I do unconsciously and compulsively are chewing the insides of my cheek, twisting my tongue around in my mouth (sometimes until it's aching), tap my fingers nervously on things around me, twist and 'click' my toes together repeatedly, tense and unclench my thighs together constantly. I'm always fidgeting in some way or another, almost always unconsciously.
I also have this compulsive habit of finding patterns in everything. For instance, when watching the TV, I am almost always unconsciously dividing the TV up into different shapes in my mind. I draw imaginary lines across the TV to divide it up into symmetrical shapes. It's hard to explain. I do it constantly and usually am not aware that I'm doing it until I realise I haven't been listening to what's going on and am completely lost. I don't just do it to the TV - I do it to windows, doors, door frames, cupboards, signs, clocks, the book I'm reading, basically anything around me that I have my attention on. It can send me into a trance when I do this. When I do realise I'm doing it, I'm usually sitting or standing tensely and chewing the insides of my cheeks or twisting my toes together in rhythm with my mind dividing up the object in front of me. Oh hell, I'm not good at explaining this. I hope I'm making sense, lol. I don't know why I do this. A sense of control, perhaps? Unconsciously 'dissecting' my surroundings? I don't know.
