Goddess needing something of a reality check (5)

I believe the answer is:

tyche

'goddess' is the definition.
(thesaurus)

'something of a reality check' is the wordplay.
'something of' indicates the answer is hidden within the clue (I've seen 'something' mean this (I've seen this in other clues)).
'TYCHE' can be found hidden inside 'reality check'.

'needing' is the link.

(Another definition for tyche that I've seen is " One bringing personal fortune".)

I've seen this clue in The Times.
