Rituals.
For years it was stand up, stumble out, scramble eggs, feed my son, step outside, smoke, wake up for "real", take a shower, really wake up for "real" & start my day. Which was usually some form of exercise with my kiddo (and another shower).
Quit smoking, no more kiddo... Getting a new ritual down was hard. Half the time I'd simply wake up and go back to sleep. Literally. For days on end. Only waking to eat and pee once or twice a day.
I had to dig pretty deep before parenthood enforced a changed ritual to look at my old patterns. When I'm doing well? I'm super adaptable, but rituals still help. When I'm doing badly, I need the structure. Something that brackets periods of time. A way to force me to shift gears (waking to sleeping, stillness to moving, work to play, panic to calm)... Because otherwise I end up stuck grinding gears. I can't shift on my own. I spin out, and grind, and overheat, and am just a solid mess. Alpha & Omega. I need a beginning and an end.
