I bought new anxiety pills. And i'd say they're working pretty well so far.
I said "i don't care" at work 3 times today. And meant it.
I even convinced one of my close coworkers not to care about something he was worried about and he went "you know what? You're right. I like the way you think" lol
It isn't a passive lethargic feeling. It's more like not giving into stressing about little things you have no control over.
