The worse feeling one can go through!! Guilt is the punishment one gets for the wrong he does but doesn't get caught. Escaping from the punishment is a yet worst punishment. The soul cannot fly, it's chained down in the dirt. Guilt is the punishment for the wrong for which you cannot blame anyone else. You struggle to lie to yourself but how will you do that? You struggle to hide, not from the world but from yourself. How will you do that? It's like a knife stuck down your throat which tears through your flesh with every breath. One feels like shaking off some moments out from life but in vain!
There's only one escape from guilt and that is confrontation!
