T-shirt Overthinking Is My Cardio | Chaos and chill vibes

Because sometimes your brain is a peaceful swing under a tree... and sometimes it's rush-hour traffic. “Overthinking Is My Cardio” isn’t just a quote — it’s a lifestyle. This unique design blends calm and chaos: one half of the brain showing a kid swinging peacefully under a tree, the other side tangled in life’s noise with a tiny car on the move. It's part meme, part mood, and fully relatable. Perfect for deep thinkers, anxious minds, or anyone who knows their brain never really rests — no matter how chill they look on the outside.
