Hi petejh,
you don't need to delete your account, but you should:
- change the password
- check the hacker hasn't sent spam or similar messages to your friends
- check in the apps if there's a new one that shouldn't be there. You might have inadvertently given access to your profile to a malicious app
Then I'd scan the pc for viruses, keyloggers and similar. Unlikely but better check.
