Lost the e-mail that was associated with an lichess account ( "unjournakamura")

Everything in the title. Is there somehow a way to find out which pseudo is linked to which e-mail adress ? For security reasons lichess asked my for a new password, but can't find or remember the original e-mail that was associated with unjournakamura

I lost my authentication to my other account. How do I fix it and use it again?

Please please, If just asking would be enough to gain access to a "lost" account, what do you think stop a thief from accessing other people accounts?

I believe you both, but for security reasons what you asking for is not feasible.

Thanks for you replies, yes it is understandable . I don't really mind to not be able to login to my other account, the only thing is that I was running into the crazyhouse wc and I'm supposed to play a match in the followings weeks or so. Is there anyway that I can complete the match but from this account ? That would be really helpfull. I'm reaching the organizer of this event to see if that's possible but I know it looks difficult
