The Health of the Dead

Reflexive idiomatic construction. The pronoun 'las' is non-referential and fixed. Emphasises self-reliance, often with a slight hint of resentment that help was not forthcoming.

Fixed expression meaning to do someone a bad service despite intending to help, or incidentally causing inconvenience. Often used with 'hacer': 'hacerle un flaco favor a alguien'.

Bodily idiom expressing a visceral reaction of dread or unease. Often triggered by death, funerals, or frightening situations. More vivid than simply 'dar miedo'.

Very common expression of exhausted frustration. Stronger than 'estar cansado'. Followed by 'de' + noun or infinitive to specify what one is fed up with.

Time-anchoring expression that implies a situation has gone on long enough that something should be obvious or settled. Often used with a note of mild exasperation.
