That's what people in Victorian Times felt when they were transported from Britain to the colonies, ie australia, for stealing a loaf of bread. Are you sure you weren't one of those in a past life. Haha.
Seriously though Mac I'm sorry you are feeling so bad. All I can say is go throw yourself into doing things out of your comfort zone. Maybe snorkeling, going into the Bush (hmm could have put that better), camel riding etc, etc, everything at the moment is in your head. Get out and live a little. Now if only I could take my own advice.
