Are the first ones that come to mind that can be used for dealing with internal anger. You could use any of them to good effect. I'd start with Self Esteem Supercharger seeing that it is usually due to a low opinion of ourself that we are angry with ourself.

Anxiety free if the self anger is caused by something outside of our control and triggers fear which in turn causes us to be angry with ourself.

New Behaviour Generator - if the anger is habitual and the actual cause is difficult to find, or has been with us some time. As in the case that we always seem to react to the same tiggers in anger.

Automatic Pilot - for putting into place a more affirmative response.
