Direct Bungie.net logins are no longer an option to log in and were phased out years ago (literally), so what you're saying doesn't quite make sense. Your only options to log in now are through XBL credentials, PSN credentials, or Battle.net credentials. When you go to log in, you have to pick one of the three, and whichever one you pick, you log in using those credentials. If you have the same email for more than one of the above, that's fine, just click the one that you want to log in with, in this case, you want to log in using your PSN credentials, so click to log in using those. If your issue is that you're unable to log in to your old Bungie.net account that was directly tied to your email, then you're out of luck, as there was plenty of time and warning to link an XBL or PSN ID to your account before the direct logins were phased out, and anyone that failed to do so no longer has access to that account; it's orphaned and archived, able to be viewed but not logged in to.
