Anger Management Support Group
Anger management commonly refers to therapeutic techniques by which someone with excessive or uncontrollable anger can control or reduce their emotions. Typical examples include the use of deep breathing and meditation as a means to relaxation. Psychologists recommend a balanced approach, which both controls the emotion and allows it to express itself in a healthy way.

I know some of it is her up bringing and some of it, (her anger,) is relationship stuff. It's funny because I always stereotype women as being open and honest but my daughter hates either talking about her feelings or hates talking to me.
Anyway you're not alone I hope you find the help you need in this.
