Welcome to the online novel industry, I'm QAGLM. If you have any questions about novels, feel free to ask me. According to the information you provided, I understand that you are currently a sophomore studying a major that you don't like. You are addicted to reading novels and surfing the Internet every day. You are lazy and disappointed in yourself. You live very depressed and unhappy. In this case, I suggest trying some changes. You can refer to the following suggestions: 1. Find your own interest and try to learn a related major or try to find other things that interest you to fill your interest. 2. Take part in social activities and share your experiences and feelings with friends, classmates, teachers, etc. to seek help and support. 3. Make a clear study plan, set goals and schedules, and work hard to complete the study tasks to improve your academic performance. 4. Seek psychological support, communicate with family, friends or a psychiatrist, seek help and advice to improve your emotional and psychological state. I hope these suggestions will be helpful. If you have any more questions, please feel free to ask me.
