How to change email for this account

Hi I just made this account. Well my PS4 and shift account are on the correct email.
But some how this account completely took up an email I use to have when I first created a PSN account.

I can’t find the option to change my email so I can complete this profile for BL3

And sorry for putting this under Duke nukem. That was an accident for some reason after the accidental click it wouldn’t let me change the topic.

This site sucks on a phone or maybe just mine.
