What is the difference between 吃不消 and 受不了 to mean "I cannot bear"?
吃不消 literally means &quot;too much to digest,&quot; so I'd use it for heavy workload, frequent annoyances, etc.
受不了 literally means &quot;unbearable,&quot; so I'd use it for unsociable people, hostile environments, etc.
But that's just my preference; in practice they are quite interchangeable.
