Resigned Acceptance

It's not a low mood, or emotional anguish, it is literally just a resigned acceptance that everything happening is too much and there's only one course of action. Not an immediate need, just a it will happen when it does. I'm still doing things I enjoy. I've called it resigned acceptance,  but really I don't know what this is. It's kinda like sitting in an armchair in a burning building and thinking "well at least it's warm."

I'm just thinking out loud, so to speak.
