You Can Trust Yourself Enough to Rest
Hypervigilance is not the same as vigilance, and this is a distinction worth making.
Vigilance is appropriate responsiveness: the capacity to notice what's actually happening in a situation and respond accordingly. It's a skill, a valuable one, and it's something you've developed exceptionally well.
Hypervigilance is something different. It's vigilance that never received the update that the threat has passed.
