I have a classmate! The expression changes quickly! ! ~ ~ a little indifference, a little enthusiasm! Does she have a split personality?

This situation is not necessarily a split personality. From the description, I feel that this child is sensitive and insecure, and has lived in an environment of fear and anxiety for a long time. Therefore, she pays great attention to protecting herself and dares not expose her true heart in broad daylight. Therefore, during the day, she will feel insecure and worry about her inner leakage; At night, we will feel safer if we can't see the surrounding environment clearly. Similarly, in colder weather, we will wear thicker clothes and tighten ourselves. These behaviors and actions will increase our sense of security, which is why this child is so different. She is always saying things she doesn't understand, which just shows that she has suppressed a lot of things inside, which may be related to her injuries. Now she is found to be in good condition and will recover soon if treated in time.
