When I create this account, it didn't ask me to provide my username, maybe I use Gmail to login and it take my email address as the handle? Now, I want to change it into something else, I read some blogs that said it is impossible to change handle. However, is there any exceptions that I require to complete some complicated things? I really want to change my handle because of my personal reasons, thanks!

Usually, you can change your handle for once during the Christmas holiday every year. And you can't change your handle to one that somebody (include yourself) has used.
Nitpicky I am, but this is not doing well for your security/anonymity. If you really wanted to stay covert, try not to give out such obvious clues to people.
Actually you can change your handle in every Christmas.But you cant change your handle to someone's handle
