Bob is right. In the example below, the email looked like it came from my email address. But when I opened it and tapped on the name of the sender, it showed who the mail was really from. This screen also allowed me to block that sender.

I received a spam/phising email from my own email address. I did report the issue to Apple via their phising email; however, now I wonder if my email address will be flagged or shut off by Apple.

The email did not actually come from your email address. It is more likely your email was spoofed by the actual sender of the email. Spammers often use email address spoofing to prevent recipients from blocking the real email address of the sender/spammer.
