What do you do when you are unhappy?

When you are unhappy, you may eat dessert, order A Mu's cake, and then go home and eat while chasing the drama. I remember one time I was very unhappy, so I went to the cake shop and bought a six-inch A Mu birthday cake. The boss told me not to write anything, so I ate it myself, and then the boss was surprised. A friend taught me this solution. At that time, we were both in junior high school. Her father always talks about her, because she thinks her grades are not good, so she is always in a bad mood at home, so she often buys a cake to eat alone. Once I went to see her, and they ate cake and watched a play together, and my inexplicable mood began to get better. So I will still do it now, and it is very effective for me.
