An aging old man in tears anxiously told me the panic in her heart: since having a grandson, should have been happy, but always worried that he would accidentally kill his grandson with a knife, such thoughts in the mind over and over again, thrown not thrown away, so they do not dare to go into the kitchen, do not dare to touch the sharp objects, all day long fearful and worried …… Further exchanges with the understanding that her fear stems from childhood traumatic experiences, when she was very young, she witnessed the scene of the shooting of prisoners, and then experienced the father because of the “stinky old nine” was arrested the whole process, the young mind planted the “can not do bad things, do bad things will be caught and shot. ” Since then, she has been careful everywhere, fearing that she might do something wrong. When she got married and had a son, she dared not enter the kitchen, dared not touch sharp objects, fearing that she might accidentally kill her son with a knife, because she thought that the child would not be able to fight back, and would be more likely to be shot because of her own carelessness in doing bad things, and that is why she was so worried and frightened. The old man’s symptoms are medically referred to as: obsessive-compulsive intention, a form of obsessive-compulsive disorder (OCD), which has the inner impulse to worry about committing some kind of behavior against one’s own will, and is still compulsively afraid of losing one’s self-control even though one will not actually put it into action. Psychotherapy for OCD is very important, you have to do it without controlling, without analyzing, without relieving your anxiety by thinking over and over again, the point is that you have to deal with the relationship between you and your thoughts, there’s a saying: live with the disease. That’s how you can really get well. When you still can’t improve your symptoms through psychotherapy, anti-strength fear medication will definitely help you.
