Breathe， take a deep breath.

深呼吸吧

Because there's nothing easier than breathing, nothing harder than breathing either.

沒什麼能比呼吸更簡單了，也沒什麼能比呼吸更困難了

When breathing is harder, pain is growing as well. But you can only concentrate on oxygenation. 

當感到呼吸變困難了，意味著苦痛也正在延續，但你卻只會專注在氧合作用上

Your body is suffering, same as your heart,

你的軀體會感到痛苦，心理感受到創傷

But you won't care, as you just want to breathe for living

你卻不會在乎，只因你想延續呼吸而存活下去
