What a week, and it's only Tuesday

Have you ever just been over it at the beginning of the week? Well that's my week ( all two days of it so far) I need a break, like a week off. In the last 2 days we have gotten some really bad news, have to move(which we knew was coming up), and both of my kids are acting crazy.
Yesterday was a holiday, so that means no school. I had to practicly bribe my 14 year old to stay home with her sister. To which she could not grasp the fact that I ask her to babysit maybe once a month. I know she has friends that babysit ALL THE TIME. Then I got calls all day long, to the point where I almost had to send my Mom over there, because of the fact that they just can't manage to act right. So I get home, and I think they are going to act right, oh no, it's just the beginning of it for the night. I really don't understand how two kids, with 7 years in between them can fight so much!
Now today I have had 2 calls from the school for my youngest. I am really just a loss for words at this point. We tell her everyday how important it is for her to listen and keep her hands to herself. We have told her this, taken away privileges, and read all kinds of books. The school suggested that we start using, Love and Logic, which is what they are using at school. The book has some really good points, but it also has some really bad reviews, so I just don't know.
What I would really like is for both of my kids to listen to me, be respectful, and for both of them to not get in trouble at school.
