Περίλυπός [2 verses] (adj sg masc nom) "Exceedingly sorrowful" is from perilypos, which means "very sad", and "deeply grieved."  - "Exceedingly sorrowful" is a word that means "very sad", and "deeply grieved."  Jesus only used it twice, Matthew 26:38 and in the parallel in Mark 14:34.

The sense here is that Christ is using this term to describe his life in this word, so "so sad" or "pathetic" might work. This phrase might be more humorous and self-deprecating than it appears. However, it is also an accurate description of the remainder of his life.
