Regret for one's actions (4-4)

I believe the answer is:

self-pity

(Other definitions for self-pity that I've seen before include "Moaning about one's misfortunes shows it" , "Excessive unhappiness at one's lot" , "(Surgical) cut" , "State of feeling sorry for one's own situation" , "Inwardly-directed compassion" .)

I've seen this clue in the Sydney Morning Herald.
