Isolation.
How often do you feel isolated by the friends around you? Feel as if you are dead and not attractive nor interesting for you friends?
What about at least one friend that love you as you are and love hanging with you because you are "dead" and "uninteresting"? Start loving who you are and you won't be worrying about no one love you because once you are who you are and comfortable with yourself, someone will definitely appreciate who you really are!
