I often wonder about the coping mechanisms as well, Withdraw... I too was frozen for 6 months, for "copping an attitude" at a graduate when I was sat down in the middle of a very real trauma I was trying to figure out. I was just so enraged that I was actually attempting to discuss something that truly bothered me, that had happened, and that this person was saying was bullshit that I had "no feelings" about! I did nothing more than shoot them a scathing look and flip off a bit at them as I was sitting down... Of course I was stood up and screamed at about my lack of respect and gratitude and then yanked down while being told I was frozen on my day. I did not even realize what that meant until I went home the FOLLOWING night to write my MI and they screamed at me again that I had written the following day down. THEN I was told that I was not moving ahead, was not allowed to talk, was not allowed to EARN talk and would be "wasting (my) fucking life" from then on. Every Monday and Friday in homes I was just stood up and ridiculed and yelled at about how I was going to go nowhere blah blah blah...
Now, the reason I mentioned the coping stuff is that I struggled with the opposite but I think equally torturous response to you while frozen because I kept trying and getting nowhere, hopelessly, day in day out, unable to get up and speak and ignored except when stood up to be ridiculed and confronted. See, from the second I was put in the program, regardless of the fact that I had been lied to by my parents and coerced into going, I literally COULD NOT put my hands down and stop at least trying to get out... because I believed I was stuck till I got myself out, because I was too certain my parents were locked in and brainwashed, because I detest violence and was traumatized by the effects of the restraints every day, because I was from another country and had no clue where the hell I even WAS, to try to run anyway (not to mention that I was there on orders of my parents and was told I would just be screwed if I hit the border because I would be sent back), and for a host of other personal reasons.
I guess the point is that I do believe that each of us has our own "hell low point" and I also think firmly that the being frozen was one of the lowest and more horrible ways of fucking with people's heads and your thread brought this back to me also...
