Objectives The purpose of this study is to understand what art therapists experience in the process of painting diary and what meaning those experiences have in the life of an art therapist. Methods The inquiry method was an autobiographical inquiry, and among the qualitative research methods, the method of narrative inquiry was used. The research procedure was conducted from January 2021 to April 2022, and the analysis contents of the art therapist's analysis process and the researcher's flower drawings and diary writing were used as artifacts. Results As a result of the investigation, the picture diary is a promise to the father, a pure record that connects the past and the present, and the image, that is, the flower painting, freed emotions and experiences. Also, although the analysis was painful, it became the basis for growth and healing, and the picture diary was a process of having time to immerse myself in my inner voice. Conclusions This investigation was a courageous challenge for me as an art therapist to look back on my life through a picture diary, and it was a process of loving myself.
