You have enough to deal with without a trouble-making sister-in-law. I would try and explain that yes, you've been through a hard time but that things are getting better. Then I would let her know that it was time for her to go home. She came uninvited so I would just give her a little push to go home. If that doesn't work then have your husband tell her to go home. You don't need the added burden of taking care of her and trying to catch everything that she's going to say to your kids. Time to send her packing!!!
