Lost access to an accounnt without an e-mail

I’m in a bit of a peculiar situation right now. I have seemed to have lost access to an account that I created (arborosetum) and I’m quite stuck since I don’t happen to have an e-mail connected to it. I can’t really provide any other proof of ownership other than the fact that I plan on using the write.as account as an extension of my Twitter (now X) account, and that I created the lost access account with the referral link from the account I’m using to type in this forum right now. Would you be able to help? Thank you so much
