Hey there BigiPadGamer,
We understand you started using Nord VPN with Hide My Email, but accidentally deactivated the email. We'd be happy to provide information to help you address this.
You can actually reactivate the email using the steps here:

2. Scroll to the bottom of the list, then select an address below “[number] inactive email address(es).”
3. Click “Reactivate address,” then follow the onscreen instructions.
Regards.
