I have changed phone although I don't really want to deep down. Anyway, I keep feeling very stressed by a lot of things. I really don't know what is the issue. I want things to be all nice and good/prefect but things are not always like this. And why can't everyone just leave me alone?

PS: I have noticed a thread/line (or maybe a crack?) at my phone back camera. Yucks! Although it doesn't affect my phone quality but I am really upset by it. And Singtel doesn't want to do a one to one exchange for me although my phone is new!
