Hi,
It's hard to be certain but I also think she isn't hungry she is seriously stressed.
I would go redad the bad shed no problem sticky and see if that helps.
Constant roaming can be a sign of stress.
It sounds as though she is "defensive striking" not trying to feed.
Double check all the husbandry, make sure they have enough tight dark hides and that they leave the snake alone for at least a week after they deal with the bad shed.
Then, if the snake seems to have settled in a bit more, try and feed it a half grown mouse ( hopper sized ).
If it doesn't eat it leave it alone for another week and try again.
