What are some coping skills for people with anxiety at night mixed with addiction and being trapped in head moments alot of the day or night if something isn't going on to give simiulation?

Hello, I'm finding the peace and quiet I seek at night to be fighting now. Especially when all lights are off. It reminds me of my time blending anxiety/mind lapses during the day; where I forget what time or even day and date it is.
Ps. I have an not diagnosed memory problem from a traumatic car wreck and accident.
