(((((((((((SerenitysWave))))))))))) I so understand what you mean. It's such a hard place to be. I'm so glad the nightmares have stopped. When I don't sleep at night, everything is harder for me during the day, even if I don't feel tired. Can you maybe get something to help you sleep at night? The only time I ever remember being fully aware and in my brain has been in T's office but grounding stuff does help sometimes.
I hope things get better soon. Please take care.
