When we interact with others, we have to battle through our own reactions sometimes. A result of this might be a feeling of guilt. As you consider the things that you do that can make you feel guilty, what are they? While you journal or ponder about these, it might be helpful if this guilt is warranted. Is it something you really need to feel? Is it something that serves you or helps you do this better? Or would things be improved if you let the guilt go?
