In psychotherapy, we often encounter clients who have had very painful and terrible experiences at some point in the past, perhaps the loss of a loved one, perhaps a sexual injury, perhaps a traffic accident, perhaps an embarrassing scene, perhaps ……, and these events hit their hearts hard, and so bitterness, uncertainty, negativity, pessimism, anxiety, sensitivity, paranoia, panic, insomnia, ……, the quality of life is greatly reduced. As time goes by, some of those unfortunate encounters fade into oblivion, and some still flash back from time to time, like a nightmare haunting. But no matter what, the resulting psychological problems are never relieved, and for that reason, psychotherapy is sought. Many schools of psychotherapy, while focusing on the symptoms of psychological disorders, inevitably involve their origin – past misfortunes. At this point, many seekers often have two attitudes: 1. It has already happened, it is a fact that cannot be changed, the damage to me has already occurred, what is the point of talking about it? Only to let me go through the pain again. 2. I really don’t want this to happen. Can psychotherapy change my past so that this doesn’t happen? It is true that the unfortunate events of the past have already happened, which cannot be changed, and the psychologist has to accept this fact. However, it is this attitude of accepting the truth that is the foundation of psychotherapy! It is not denial, it is not avoidance, it is not fantasy, so that the psyche is not distorted! What is the point of psychotherapy when faced with the fact that the past cannot be changed? Psychotherapy provides a stage for the seeker to change the past! On this stage, the psychologist will go back to the past with the helper and experience the suffering, and the helper will no longer be alone. In the face of the loss of a loved one, the psychologist will help the client to relieve the complex emotions of grief, fear of leaving the loved one, and complaints about irresponsibility of the loved one. In the past, the helper was suffering from the repression of “not being able to say anything”; when faced with some embarrassing scenes, the psychologist will experience the embarrassment together with the helper and look for its root cause instead of just avoiding it. In this sense, it can be said that psychotherapy can change a person’s past, and in the company of a psychiatrist, one can re-live a hurt past, so that psychotherapy can bring pain; however, it is a new past, and with the help of a psychiatrist, one can deal with the emotions at that time in time, and in the most painful time, with the company of a psychiatrist, one is bound to have a new experience. And it is this new experience that will bring the help-seeker a new attitude and perspective, all of which is accomplished in the course of psychotherapy. In this sense, it can also be said that it is not psychotherapy without going back to the past. As psychotherapy progresses, the client slowly moves from the past to the present, and at this point, the client is a completely different person than at the beginning of the therapy, a grown-up real person who can handle his or her own problems in a mature way, and the time has come for psychotherapy to end.
