God said:
I ask you:
What emotion are you going through right now? Irritation? Outright anger? Are you kicking yourself because you didn't speak up for yourself, or kicking yourself because you spoke up too much?
Either way, you may feel you are in a sorrowful shape. Whatever you're upset about now, walk through to the present and correct it. What you accomplish is tantamount to reliving anguish and reliving it again. You're good at reliving it, yet not good at all at getting rid of it once and for all.
You would give a lot not to be the fool you have been. Kicking yourself doesn't express the weight of the burden you carry. Beating yourself up doesn't say enough.
What is it exactly that you are trying to undo?
It has been said that whatever it may be you are upset at, it is really something else. Perhaps, if you knew what the cause of this anguish really is, you could throw it away once and for all. Well, not so much throw it away as to rise above its slings and arrows.
What is this guilt you carry that is unbearable to the point that you suffer for it again and again? It is not cut and dried. For some it is what you are guilty of letting slide, perhaps under the mask of not hurting someone's feelings yet masterfully hurting your own. And for some, it is putting your feelings before someone else's feeling, and then regretting this. Your theme may be: "With rue, my heart is laden."
One way or another, you rue and rue again, and what the whole basis for this really is, no one seems to know.
