ACIM teaches that "all anger is an attempt to make someone else feel guilty".  
If this is true, to be "angry at myself" first requires that I regard myself as "someone else"!? Several places in the course suggest that we project a "self" that is an image we have chosen for some purpose, but not our true Self which is of course, God-given and immutable. What could possibly be the purpose of projecting a "self" which I choose to see as guilty? Could it be that I prefer that self be guilty rather than accept guilt into my preferred "self"?
    
It all begins to sound like some kind of avoidance "con" game. How many "selves" do I think I have? Possibly a lot!  I might just generate them as needed to hide from any kind of responsibility!?
    
Rather than attempting to shuffle guilt off onto some projected self, why not just "look directly at the seeming source" of guilt. If one chooses to do this, accompanied by Jesus, all sources of "guilt" can be seen in the light and will simply vanish in Jesus' loving acceptance. Then, one has escaped guilt, not by projecting but by re-interpretation a far better cure than attempting to blame other "selves".
    
The Course is unique in my experience in proposing this approach to problem-solving. Rather than denying error, or cathecting error (release through catharsis - discharge of tension) it simply offers the total love-encompassment that Jesus provides and helps us re-understand the error, rather than struggle with the guilt induced by attempts to hide or overcome it. In other words, "don't fight it -- release it!"  This leaves one with a loving appreciation of oneself rather than angry attack.
