Your daughter is full of anger, and rightly so. I think it's good she's at least letting her anger out.
My W is a marriage and family therapist, who specializes in helping children deal with family trauma, and I've been her informal sounding board over the years. I've heard a lot about cases involving kids dealing with exactly the kind of anger your daughter is dealing with.
I think your daughter would get tremendous value from talking with a good talented family therapist. If you go that route, make sure it's someone experienced in working with teens. Maybe her school can recommend someone. She can learn to process that anger in healthy ways.
