Unhappy Saturday

Things have changed abit since i have came back. Doesn't feel this way when i am back from Europe when i was there during my Summer camp in Paris, France. Doesn't feel this way when i came back from Shanghai, China after half a year. Why now? Is it because it has been so long? I wonder. I do hope that things will get back to the time before otherwise i really dun wish to come back and learnt about the truth now.
