One afternoon when I was in the clinic, a very anxious mother came to my office with her three-year-old girl in her arms, saying that her child had been biting her lips incessantly for the past half a month, so much so that her lips had been bitten and swollen. She went to the pediatrics department and could not do anything about it. She went to the stomatology department and was advised to pull her child’s teeth, and finally the pediatrics department advised her to go to the psychology department. Seeing the poor little elf in her arms and the anxious mother, I am also a mother of a two-year-old child, I can very much understand her feelings, but I really can’t do anything about this child’s situation. Because I am a psychologist, I have been dealing with adult patients with mental illnesses for more than a decade, but I have not been involved in the psychological aspects of children. I really felt guilty and frustrated, and I really wanted to help her. After work, I searched everywhere for information and consulted with my peers, and finally found the answer that the child was suffering from a childhood mood disorder. In my spare time, I reopened developmental psychology and child psychiatry, and felt that I had gained a lot and had become interested in child psychology. When I decided to go to Beijing for further training in child psychology, my friends around me didn’t understand, “You are an associate chief physician, and your children are so young at home, why do you bother? It is said that children come from heaven, they are angels, they are also hurt at times, I want to help these hurt angels. Fortunately, my decision was supported by Da-Dian’s (my son’s) father, so I went. During this time I also felt very hard and missed my children and family, but I really learned a lot. Whenever I came back and saw the children’s symptoms improving and the smiles on the faces of the moms and dads, I knew I had really made the right decision. May my decision help more angels, not only with the heart of a doctor, but also with the heart of a mother.
