Guilt

Guilt is the root cause of self condemnation/self blame. It might be that you sub consciously telling yourself that you MUST achieve something or SHOULD do something. but in the 1st place no one has says u need to do all these things.

Guilt also could be formed by the perfectionist in you. You might feel bad, inadequate or incompetent when things are not done perfectly. But who say u must be perfect in everything you do, if everything is perfect, there would be no room for improvement. Most of the time, perfectionist usually lack of self confidence.

It could be also when you violate your strongest values, your mind sends you a message of disapproval ;telling you that you should not have done so.

You might be carrying over the responsibility of other people's suffering.if so you might feel responsible for other people's suffering regardless of whether or not you are guilty of any wrong you will experience tremendous amount of guilt. No one should ever feel responsible for others suffering because only the sufferer is responsible for his life and not you. IT'S NOTHING ABOUT YOU.

My word of advice is that, don't take responsibility which does not belongs to you. Admit what you have done wrong, forgive yourself because no one is perfect. Let go and move on!
