Answer

'so regret'.
'so' preceding 'regret' is stressing or emphasizing that regret.

Answer

normally for using "so" as an intensifier or in place of "very' we place it before whatever is being intensified.
"so regret" would be the most natural, but you can place it after, it becomes like an afterthought in this position.
