I sat down with a friend of mine the other day, a really beautiful woman who appears to live a very glamorous lifestyle on Facebook - and she admits that she shares many of the same sentiments in this thread - that her life day-in-day-out is monotonous and she's not really doing anything with her life. Her life is boring, stale, and she's just existing, not really living. She also did the poor-little-rich-girl rant of how she doesn't have any real friendships and all her friends are fake and no one really likes her for who she really is.

It's a common existential problem with the human race - to feel leaden and dragged down, to feel as if you're just alive, but not really living. Unless it's serious dysphoria, I would say that you should examine your mood state - and take appropriate steps to address it.
