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

'boy upset about mild phobia?' is the definition.
I can't judge whether this definition defines the answer.

'trivial stuff' is the wordplay.
'trivial' becomes 'no' (I can't explain this - if you can you should believe this answer much more).
'stuff' becomes 'things' (I've seen this in another clue).
'no'+'things'='NOTHINGS'

Can you help me to learn more?
