Mistakenly Disabled My Apple ID – Need Help Restoring It

I recently lost my iPhone and, in the process of securing my account, I mistakenly disabled my Apple ID. Now, when I try to recover it, I get the message: "This Apple Account is not valid or not supported."

I’m certain this is my correct Apple ID, but I can’t access any recovery options. Has anyone experienced this before? Is there a way to restore my account, or do I need to contact Apple Support directly?

Any guidance would be greatly appreciated! 🙏
