do the 'sandwitch' method. it works all the time. tell your daughter the good stuff about her, the possitive stuff she made. then tell her what things she should've done right or how she can make things better. then tell her again to keep up the things she's doing right.
indeed it feels bad to be pointed out by everyone. tendency is to retaliate and deny everything, especially for teenagers...
best of luck. hope you and your daughter will get along.
