I think the most important thing is mentality! If you don't change your mentality, you can't get rid of negative psychology. Since you are not happy, then think about happy things first, or change the environment and go travel to be happy. Or find two or three close friends to express your heartfelt feelings and tell the unhappy things. Don't keep them in your heart. Set a goal, no matter what it is, you must have a goal. At least you have a goal to live towards. What do you want? What do you want? What state do you want to achieve? Whether it's for yourself, your family, or others, in short, this is the support for a person's life. Only when you have a goal will you find ways to change yourself and work hard. The mentality will slowly change.
