You can update your email using your preference settings. If you haven't already done so, you can just rename your account rather than creating a new one. If you have already renamed your account (and thus can't rename it again), you don't necessarily need to disable your old account to create a new one. However, if you do need to create a new one and you do indeed want to close the old account, then you can as described on Help:Closing_an_account.
