Let me use my Apple ID

Why? You can permanently delete an Apple ID, but be aware that no one (even you) will ever be able to use that Apple ID again.

How to delete your Apple ID account - Apple Support

You must delete the Apple ID from within that Apple ID account - you cannot use one Apple ID to delete another.

All purchases made using an Apple ID are tied to the ID. Delete the ID and you will need to download them using your new ID.
