The prospect of 30 more days/nights like this scares me. I've read about what's called nocturnal angina and seems to describe it.
a long time ago I was regularly in situations where I felt unsafe and was (reasonably legitimately) concerned that something was going to happen (not death but somewhat fearsome).
I decided that if it happened it would happen and I would deal with it then, if it didn't happen why should I sit around in fear? Minutes stretch in distorted time and hours of that passes slowly.
I decided to just stop worrying about it and look out the window or think about what interested me (usually something technical).
Years later I was reading Dune and came across that "litany" and it struck a chord with me ... a chord of "we both saw that".
Years after that in the study of Stoic philosophy I learned of Epictetus and also felt a commonality of harmony in thought
Stoicism is not a religion, it is a life philosophy. It is (curiously) maligned by religious groups and described as what it is not. One such depiction is that it encourages
feelinglessness (personally I'd attribute that more to Buddhism).
I see it as a way of looking at your genetic inheritance as being the descendant of those who survived; making you a survivor. A way of looking past problems and only at either solutions or acceptance.
Seneca is one of the greats:
worth reflecting on that...
Myself I think the best modern introduction to Stoic views is in this video:
if you find yourself awake and have time, I suggest you watch it and see if you can find something in there to help calm and quiet your inner bell (which is rung by the impacts of concern for what may be).
Best Wishes
