Funny to learn this word today. Stuff have been pretty rough for me these past few month and I have been unknowingly practicing ataraxia. Problems (at least mine) are temporary, instead of lamenting I should stay cool and enjoy what I have, preparing for the better days. It's truly liberating.

In Epicureanism ataraxia is paired with ἀπονία (aponia).

Aponia is for the body what ataraxia is for the mind. You can find more details in the Wikipedia page about Epicureanism [1]. True pleasure comes from the absence of spiritual trouble and the absence of physical pain. The Latins used to say "mens sana in corpore sano" (healthy mind in a healthy body)

Next question / consideration in your situation of course is whether it's ataraxia, indifference, stoicism, emotional numbing, or disassociation. I think they're probably all related concepts.
