Meeka's "Okay" is about the gap between how someone feels and what they let others see. The speaker says they're almost never happy but not exactly sad either, and the anger, exhaustion and worry pile up until they feel like they're sinking. Short rhyming couplets give the poem a quick, restless rhythm, which suits a mind that is "always overthinking" and "head always spinning."
The speaker feels like a failure, pressured to be productive, and unsure of their future. They can't even name the problem, wondering whether it's "depression or burn out." There's a brief moment of pleading for help, but it passes quickly.
The ending is the heart of it. The speaker hopes things will improve someday, yet "for now if anyone asks I'm okay." The title now sounds like a mask. The mood is tired, anxious and quietly lonely, with a small thread of hope that never quite lets the speaker ask for support.
