Ignore help and try breaking toenail (2,2,5)
I believe the answer is:
go it alone
'ignore help' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'try breaking toenail' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'breaking' indicates an anagram.
'toenail' is an anagram of 'italone'.
'go'+'italone'='GO IT ALONE'
'and' is the link.
Can you help me to learn more?
(Other definitions for go it alone that I've seen before include "Act independently" , "set up as freelancer" , "Take something on on one's own" , "act unaided" , "Proceed without the help of others" .)
