When was the last time you said "I'm fine" and didn't mean it?

Literally every day but the most recent one was 1 hour ago, my friend texted me, and she asked me how was i? Of course Like any decent friend I said "I'm fine/ok". I genuinely am not, I'm confused, tired, depressed, lonely.. but ofc I wouldn't tell her because I'm used to saying I'm fine and she still wouldn't understand if I said I'm not, besides I'm still fine.. I mean, I can still stand up, wake up, smile, laugh, so yes.. I guess. I'm fine but not quite
