'it seems to me' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'one horribly sad year' is the wordplay.
'one' becomes 'i' (Roman numeral).
'horribly' indicates anagramming the letters (a horribly wrong version of the letters).
'sad'+'year'='sadyear'
'sadyear' is an anagram of 'daresay'.
'i'+'daresay'='I DARESAY'

Can you help me to learn more?

(Other definitions for i daresay that I've seen before include "Methinks it's likely that" , "Probably" , "Maybe" .)
