I don't know how to change my apple ID (i forgot my my current one and the password)?

I forgot my e-mails password. Secret questions and the password of the alternative e-mail so i can't use it anymore (that's my lie to make it simple)
somehow i managed to add an e-mail to my apple id list of e-mails
(in attempt to replace it / change it)
in my iphones settings it says my new e-mail is the apple id
but when i download apps from appstore
they ask me for my old apple id's password which i forgot
what do i do?

You have two simple options.

1.To get your original apple ID back, you must call apple. You can't do it over the internet because they won't be able to identify you.

2. Make a new apple id

Here's an article from Apple.com on "Apple ID: Changing your Apple ID"
