想他想到连呼吸都是疼的
[xiăng tā xiăng dào lián hū xī dōu shì téng de]
Translates to 'missing him to the point that even breathing hurts.' Exaggerating to express profound loneliness and longing for someone absent, emphasizing the all-encompassing nature of longing so intense it becomes physically painful, similar to expressions like 'hurts to breathe'.
