Woow! tough times indeed.
As much as possible, turn difficult things into games. Like - instead of trying to train "dont walk down the stairs in front of me you clumsy clod" train "lets play that game where you get to run down the stairs into mom's arms, which you can only do if you wait at the top of the stairs while mom walks down".
OK so maybe you dont have that problem, but you get what I mean

. Instead of feeling the need to impress obedience on the dog, which can be frustrating for both parties, its often possible to turn things into a game which achieves the same outcome but is not so stressful.
You did not mention so many specific things that she is doing so its difficult to suggest training games...
I would simply remove any kind of bedding that she can tear up, replace with something which does not matter so much (cheap blanket). Give her lots of great things to chew - big meaty bones, kongs etc.
