I believe you about the breakdown, Tinkerbeau, and I do know exactly how you are feeling, as I have been there. Too tired to move, too anxious to sleep, the pacing, and the agonizing feeling that all may be on the brink of loss. These feelings are real but are brutally enhanced by the effect of coming off the alcohol.
Can you muster up the act of getting into a shower, getting dressed, and then go out to get some help? Your mind needs some relief, as well as your body does, and that is not going to change until you do something positive. You might be surprised at just how much better you would feel off if you do.
