heartache

I'm a little stuck... Click here to teach me more about this clue!

'form of distress' is the definition.
'heartache' can be an answer for 'distress' (I have seen 'Emotional distress' mean 'heartache' so perhaps 'distress' could also mean 'heartache'). I am unsure of the 'form of' bit.

'compassion affected each' is the wordplay.
'compassion' becomes 'heart' (I've seen this in another clue).
'affected' is an anagram indicator.
'each' anagrammed gives 'ache'.
'heart'+'ache'='HEARTACHE'

Can you help me to learn more?

(Other definitions for heartache that I've seen before include "Great sadness" , "mental anguish!" , "Emotional distress" , "Agony of Love" , "Suffering" .)
