She tends to only label her negative emotions as anger though.
My old MC said that this is common. Anger is a secondary emotion covering up a primary emotion (like sadness), but it is usually easier for us to deal with the secondary emotion so it comes out as anger instead.
And she very well could be testing you to make sure that you still feel remorseful for what happened. Good for you for validating her feelings and showing her that she can trust you!
