冰冷的感觉正在蔓延到心脏
[bīng lĕng de găn jué zhèng zài màn yán dào xīn zàng]
Translates directly to 'The cold sensation is spreading to the heart.' Used metaphorically, it represents feeling increasingly disheartened, isolated, or detached, expressing feelings of coldness moving from body parts outward or internally until it seems to reach the core, indicating depression or despair.
