1) Everything you have ever experienced (emotionally) was felt by a mass majority of people. Each heartbreaking experience could basically be understood by the strangers sitting next to you on public transit. When you begin the start of a painful story, generations of people could finish the ending because it seemed so familiar to them.
2) All of the key moments of your life were 100% unique. Your closest friends could not even fathom what you've been through. There isn't a message board for your experience. You are essentially alone in your human experience.
