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

'keep returning upset crazy' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'about lifesaver on island?' is the wordplay.
I cannot really see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is located in the answer.
'island?' could be 'elba' (Italian island) and 'elba' is located in the answer.
The remaining letters 'dom' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
