Happy one day, sad the next

Was going to write about other stuff on my blog today. But the news is basically filled with the bombing in London. It comes just one day after London was announced as the host for Olympic 2012. Imagine what would have happened if this bombing happened even a day earlier? Would the voting still continue on? Would London still be the host nation? Stopping to wonder, whats wrong with the world? Is this the natural way to get rid of mankind? Why is that man never learn from history? Is all this violence really necessary? Is the death of so many innocent people, some of whom are tourist, really worth in this tick-for-tack world? Its horrible looking at the pictures from London. People all bleeding and bandaged. A double-decker bus becomes a single-decker bus. Scary scene.
Away from the national news and back into my life. Kind of looking forward to going back home for good. I know I will miss this place when I eventually go home. Gotten used to the life here. It would be sad to leave all my friends behind here and also the people in my lab. But going home, everyones there. Family and friends. Reckon its still home and prob where my life and heart is. Suddenly missing my life back home too. Guess its just the time to go home thats all. Afterall, I have been here for almost 2 and half yrs. Everytime I go back I realized that regardless of how much I have enjoyed my life here, I still miss all the time with my friends. Everyone have moved on with their lives too.
Have also been feeling very stressed out and tired emotional. I suddenly just felt that I want to get out of Brissy. Too much going on these days. I just feel like everyone around me is making me emotionally taxing. Regardless of which gp of friends I hang around with, where I turn, I get this feeling. Its not that I don't like to offer a listening ear to others, I know Singaporeans here should all stick together and help one another out. But its come to a point where I'm really tired. Also there are people here who make me feel like I have to be selective as to what I say and do. I get questioned for things that I say. It becomes a very confrontational atmosphere and I start feeling very defensive and aggressive too. I kinda feel like I am living in Big Brother house. Thats just how I feel about my life now. Maybe all these feelings come about from all the problems that I have to face with everything that I have to do to settle things here before I go home. Simple things like selling the car to settling the house and all these stuff that just put a strain on my mood I guess. I really need to go for a holiday and looking forward to my family coming over next week and out trip to Adelaide.
So is this strange mood that I am feeling due to the reason that I am going home? Maybe subconciously I am feeling a certain feeling that I have not identified? So many questions and no answers.
