What the Heretic said. Take a deep breath, relax. OK: If you genuenly suspect fraud…
1) Call your bank; ask about cancelling your account(s) and moving your money to a new one. You’ll probably have to go to a branch in person tomorrow (paperwork, passwords, etc.)
2) Perhaps cancel your ATM/debit card(s) – request new ones. While you’re there, withdraw some cash to hold you over until the new card arrives.
3) Set up a new eMail account and contact the compromised eMail provider. Explain the situation. Hopefully they can recover some of your eMails before they close the account.
4) For now, alert only close friends and family of your new eMail address.
5) Contact support here at Fluther and they may be able to retrieve you account (or at least screen name) and set you up on a new account.
6) Calmly think of any other accounts/memberships etc. that may be compromised by somone accessing your eMail. Contact them and shut those accounts down orchange passwords if you can.
Don’t panic. It’ll be OK.
