I believe the answer is:

tried

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

'attempted while' is the definition.
'tried' can be an answer for 'attempted' ('try' can be a synonym of 'attempt'). I am unsure of the 'while' bit.

'terribly tired' is the wordplay.
'terribly' indicates an anagram.
'tired' anagrammed gives 'TRIED'.

Can you help me to learn more?

(Other definitions for tried that I've seen before include "Had a crack" , "Endeavoured" , "Put to the test" , "Made an effort" , "Attempted" .)
