Login Credentials Expired?

How am i supposed to reset my email when my email isn't even linked to my Xbox account when signing into ea.com? my xbox email is the same for xbox.com and microsoft.com neither of those 2 websites have my password been changed on, my email/password when logging into my Xbox account has only been changed on ea.com, which literally makes no sense since i use the Xbox option to sign in, like how in the world where they able to change my Ea details without getting my Xbox account itself. And when going to the Ea launcher on my desktop it puts me on the "log in/sign in" page and since i use my Xbox account to play the game i use the the option to sign in with Xbox, and after that it loads for a second then takes me to another page that says "Enter the email address, EA ID or phone number of the account you want to change or set a password" when trying to use my Xbox email which is "[edit: email address removed]" i get this message "We couldn't find your ea account" and then when trying my main email since it's also linked to my Microsoft account which is "[edit: email address removed]" and got the same message but when putting in the name for my apex account which is "Z3RU3L" i get this.... "We'll send a verification code to [edit: email address removed] and by the two other emails I've mentioned you can probably figure out that I've never seen this email before so there's no way for me to reset the password. Even when going on my friends Xbox itself i can login into my Xbox account but, when going to load up apex it also pops up the msg saying i need to reset my expired password (thought maybe my pc at the time was just acting up) so my Xbox account itself is fine, it's just my apex account that's got compromised. Also when going to xbox.com i have a order in my purchase history where i bought apex coins, idk how much help that can be but ive seen people say being able to show proof of purchase could help.
