Uh the thing is, i dont remember it, as i cannot see it currently, i also sadly do not have access to discord because of some restrictions, the username is Lyrikelyly, i just wanted to know if there was a way i could request some sort of email change

So when i made the account "Lyrikelyly" i might've used a tempmail because of the whole "you cant make an account" thing that was happening (i had no other emails and it was bugging and wouldn't let me make another account) Is there a way i can change the email/request a change for Lyrikelyly?
