In the creation of the novel, the performance of the character's hidden depression can be presented in a variety of delicate and layered ways, and extreme behaviors can be used as the climax of the inner struggle.

Hide the daily manifestations of depression** 1. **Social mask** -Act cheerful and talkative in public, but instantly tired when alone, his smile disappears. -Use humor or self-deprecation to cover up your true emotions, such as joking "I'm fine, I'm just lazy." 2. **Changes in body and habits** -Insomnia or drowsiness, the character may rely on drugs or alcohol to help sleep. -Sudden loss of appetite or overeating, obvious changes in weight but deliberate concealment (such as wearing loose clothes). -Overwork or exercise, paralyze yourself with busyness, refuse to stop and think. 3. **Avoidance and alienation** -Suddenly cancel the party plan, on the pretext of "something is wrong temporarily" or "too tired". -Loss of interest in things you once loved (such as giving up hobbies or perfunctory invitations from friends). -Avoid in-depth conversations and change the subject when asked about your feelings ("I'm just a little busy recently"). 4. **Subtle abnormal behavior** -Repeatedly organize items or clean the room (obsessive behavior relieves anxiety). -Self-harm unconsciously (such as pulling nails to bleeding, biting lips). -In a daze for a long time, or overreacting to small stimuli (such as trembling due to the sound of closing the door too loudly). --- ###**2.
