Notice my upset in fortune produces one feeling superior (4,4)

I believe the answer is:

lady muck

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

'one feeling superior' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'notice my upset in fortune' is the wordplay.
'notice' becomes 'ad'.
'upset' indicates anagramming the letters.
'in' indicates putting letters inside.
'fortune' becomes 'luck' ('luck' can be a synonym of 'fortune'**).
'my' is an anagram of 'ym'.
'ad'+'ym'='adym'
'adym' going within 'luck' is 'LADY MUCK'.

'produces' acts as a link.

Can you help me to learn more?

(Other definitions for lady muck that I've seen before include "Socially pretentious woman" , "Woman pretending to be an aristocrat" .)

I've seen this clue in The Telegraph.
