心烦意乱 (xīn fán yì luàn) — to be terribly upset and confused; to be agitated and anxious

A drawing of the thing itself, worn down over three thousand years into a few strokes.

The shape of 心 comes from a drawing of a heart, now highly stylized.

Two or more meaningful parts placed together so that their meanings combine into a new one.

This origin belongs to the traditional form 煩; 烦 is its simplified writing.

In the traditional form 煩, the shape is made from 火 (fire) and 頁 (head).

No reliable origin is recorded for this character.

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 亂; 乱 is its simplified writing.

The traditional form 亂 contains 𤔔, a drawing of combing tangled threads, and 乙; the simplified 乱 is only a later shorthand, not the historical shape.
