Loneliness is something that, even though I have a lot of friends to depend on as I am quite lucky to be, I could learn to be used to it. Usually since I am most of the time in the virtual world playing with other people, this takes my mind off being lonely, as I always have someone to play with it.
Heartbreaks is not one thing I have ever experienced, so I could not really comment on that.
Being different from my peers, that is something that most people doesn't want to be, but I for one, want each of us to have our different identity, for us to be what we are. This differentiates us from our friends, and to impress them too.
