Can't get back my account

[Utente2]

Hi I'm writing this with a throw away account I made with another email to report that I lost my username and password to another account. I still have my email, I tried multiple times trying to get back my password with my email (Because the instructions said that I can use either my nickname or my email) but it kept getting denied. I even tried making a new account with that email (To see if I didn't use it in the first place) but it told me that it was already in use. I asked for help in discord and they told me to come here with another account. I wanted to know if I can back my account with my email or if the original account (to which the email is associated) can be deleted to make a new one.

Thanks for the help

Ps. I won't write my email in a public post but if asked I'll obviously tell it in private chat.
