It happens that mistakes made by a person in the distant past haunt him. Again and again, in his thoughts, he returns to past events, suffers from shame, resentment and the inability to turn back time. If you have the same situation, find a way to find inner harmony and let go of what was once.
Analyze
It happens that a person, remembering some event, returns to one moment, then to another. He suffers from the mistakes he has made, but does not try to assess the situation as a whole. If you want to let go of the past, do a detailed analysis of what happened. Consider all circumstances. Try not to judge yourself harshly and look at your own behavior as if from the outside.
Surprisingly, some people are much more lenient with other people's misconduct than their own. If this is your case, imagine that someone else made your mistakes, and think about how you would rate what happened and the guilt of the main character in the story.
Consider the motives that drove you. Sometimes people easily judge themselves in the past, forgetting that then their thoughts and feelings were occupied with other things than in the present. Do not think that you were worse in those days. You just had different circumstances from today. You shouldn't be so self-critical.
Negative character
Sometimes the past torments those who strive to be the best in everything and everywhere. Such a complex of an excellent student or an excellent student makes it difficult to forgive oneself for some wrongdoing. You are not perfect, and neither are the people around you. Take it for granted. Stop being tormented by the fact that you did something wrong or allegedly ruined your reputation.
Allow yourself to be bad, suppose that at some point you went against the society, the system. If all is well now, why be tormented by the past? Yes, you followed the lead of your own weakness, yes, you have vices, that is the kind of person you are, no better and no worse than others. Making this assumption helps you deal with pain and guilt. It is worth clarifying here that we are not talking about the need to build one's own shortcomings into a cult, but about a way to forget about the past through self-acceptance.
A voucher for the future
It is important to learn a lesson from a situation that haunts you. Perhaps you are unsure of yourself, do not trust yourself. Draw the right conclusions from what happened and correct your own behavior. If you can't do this, you probably need to seek professional help. After all, when an individual understands what exactly prevents him from living, but cannot fight it, the process of self-destruction starts.
Maybe your anxiety about past mistakes is understandable, and you are simply afraid to find yourself in an unpleasant situation again. A support group and willpower can help you cope with a difficult situation. The main thing is to believe in your own capabilities and the fact that you can free yourself from the past.
