How to change my Email in Minecraft if I don't have access over the mail? T-T?

I made my Minecraft account with my school E-mail, However when i moved away from the school, they deleted my mail, and now I can't change my email in Minecraft. Even though I tried migrating my moang account to Minecraft and almost so I can change my email, I can't't since its asking me to verify if with my old E-mail…

I Really want to change my mail… Can anyone… Please… Please.
