Livestrong.com: Guilt

What is guilt?
Guilt is:

* Feeling of responsibility for negative circumstances that have befallen yourself or others.
* Feeling of regret for your real or imagined misdeeds, both past and present.
* Sense of remorse for thoughts, feelings or attitudes that were or are negative, uncomplimentary or non-accepting concerning yourself or others.
* Feeling of obligation for not pleasing, not helping or not placating another.
* Feeling of bewilderment and lack of balance for not responding to a situation in your typical, stereotype manner.
* Feeling of loss and shame for not having done or said something to someone who is no longer available to you.
* Accepting of responsibility for someone else's misfortune or problem because it bothers you to see that person suffer.
* Motivator to amend all real or perceived wrongs.
* Strong moral sense of right and wrong that inhibits you from choosing a "wrong" course of action; however, you assign your own definitions to the words.
* Driving force or mask behind which irrational beliefs hide.

Admittedly, I am one of those who takes on too much. (Guilty!) I often take on responsibility for things that aren't mine. But the other day when I had one of my "episodes" of guilt, I was able to work through it. At least mostly. Guilt can be a great "check" on you; you can right wrongs. Yet there are some who feel no guilt at all, about anything, and perhaps have no issue with doing things that might lead to a feeling of guilt, such as robbing a bank.
