Due to Minecraft deleting everyones logins on launcher, I changed CypriotMerks email long time ago and never noted it down because I never expected something like this to happen and I happen to forget the email. I've contacted support so hopefully I get my account back. The email is connected to my other email so hopefully I can contact hotmail/gmail to see if they could find what emails are connected to my original email.
Try searching for a confirmation email, or something of the sort, in a few e-mail accounts you have, might get lucky and find the right one.
