You don't have to wait long until the next story comes out about some famous person who commits suicide or hits rock bottom in some other way. The average person thinks 'why would they do that when they have so many friends?'.

The reality is that even though they might have thousands (or millions) who know their name or will act really excited to see them at their next cocktail party; they have no one to turn to in their real moment of need. They simply don't have deep, long lasting relationships with people who genuinely care about them. They are surrounded by 'suck-ups' who will tell them what they want to hear instead of having a real conversation with meaningful content. When they are in real trouble, all those 'friends' will abandon them at the drop of a hat.

The online world mimics that situation very well.
