I'm upset tolerant outlook lacking King's English (3,2,2)
I believe the answer is:
woe is me
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for woe is me that I've seen before include "I'm done for" , "I'm fed up" , "I feel terrible" , "I'm dismayed" , "Alas and alack!" .)
