I believe the answer is:

dole out

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

'share the burden' is the definition.
'dole out' can be an answer for 'share' (thesaurus). I am not certain of the 'the burden' bit.

'with assistance unavailable' is the wordplay.
'with' means one lot of letters go next to another.
'assistance' becomes 'dole' (dole is a kind of assistance).
'unavailable' becomes 'out' (I've seen this in another clue).
'dole' put next to 'out' is 'DOLE OUT'.

Can you help me to learn more?

(Another definition for dole out that I've seen is " Apportion".)

I've seen this clue in The Telegraph.
