I always find at about 3-4am, alone, dark, quiet rocking and biting my tongue to try and not wake anyone, to be the loneliest hour. Without the dark/black/gallows humor might not have made it this far. I have help from family and while the is freaking amazing, the depth of the pain is really isolating because it is basically unimaginable to anyone who has not experienced it.
I tend to try and blast music or force myself to play something, if it allows me, to try and split my focus. Adhd is kinda a blessing in those cases if I can manage to grab my hyperfocus with something, it can in essence put me in a fugue state and helps to ride out the hellstorm.
