I used to think that being alone is humiliating. Therefore, I often cater to those relationships that are not suitable for me at the cost of consuming myself. It was not until my undergraduate classmates chose to end her life by drowning that I realized the impact of negative emotions on individuals. I firmly believe that all the beautiful words in the world can be used to describe her. She was considerate, friendly and warm, tender, kind and gregarious. Perhaps it is these beautiful words that make us unable to perceive her inner pain, and also make her repressed mood be destroyed. At that time, I often recalled her. In order to get out of the hard time, I learned a lot about psychology. Through this process, I found that negative emotions and happiness will accompany each of us all our lives. They are not shameful. I am very grateful to her help. In memory of her, I take the loneliness I feel as an example, hoping that the audience can face it and learn to adjust, so as to reduce the occurrence of such stories.<br/>
