Being social is not something that comes naturally to everyone. Some people just hate it. If you fall into this category, it can only mean one thing - you are an introvert. You enjoy being left alone. I for instance prefer being alone to being with others. It is nothing abnormal; it is who you are and how you were made. But if being alone is affecting your social skills and entire life, maybe you should go out more often. It can be hard sometimes, but if you hang around some people you like and do what you enjoy, you can improve your social skills.
