Surely such anger could be appropriate, too; it need not always, or even more times than not, reveal an implicit "fault" (something for which you must do work) in you?
I completely agree.
For me, I've come to learn that I often feel (create) anger when I'm resisting what is and then ask myself, how futile is that?
