Loneliness

How is it possible to feel lonely when you are surrounded by people and most importantly, friends whom you can talk to and share with? I find this very weird because I only feel this loneliness when I am in Perth. It seems being busy couldn't get rid of it. I have three projects this semester and yet I still feel restless at times. Moreover, the loneliness I feel makes me dislike to be alone or even doing things alone such as going to the library alone. This is crazy. That's it!!! I am going to drag myself to the library. tata ....
