I accidentally deleted my email that I used through my Apple ID, iCloud, etc.
So I happened to delete the email I have been using for my Apple ID and iCloud, I can't get it back but it is still being used for my Apple ID and iCloud but now because it's deleted and I am having trouble changing it to a new email. I changed my Apple ID to my new email and updated the password but I can't sign into things like iTunes because it asks for my old Apple ID and I tried everything like signing in with my old one, my new one, and none of it works. I also am not sure if or how I can change the email I'm using through iCloud, I am not so sure how it works with other things like Apple IDs.
Basically, I need to know how to make sure I can sign into everything (Apple ID and iCloud) with my new email by successfully changing those accounts from my old deleted email.
