Response I'd prepared is a little hollow (10)

I believe the answer is:

depression

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

'little hollow' is the definition.
'depression' can be an answer for 'hollow' (thesaurus). I am not certain of the 'little' bit.

'response i'd prepared' is the wordplay.
'prepared' indicates anagramming the letters.
'response'+'id'='responseid'
'responseid' with letters rearranged gives 'DEPRESSION'.

'is a' is the link.

Can you help me to learn more?

(Other definitions for depression that I've seen before include "Pit" , "Blues" , "Bad times" , "gloom" , "mental anguish" .)

I've seen this clue in The Irish Times.
