i want to delete my apple id

If you cannot log into it, you cannot complete the request to delete it. Being able to login is essential for proof that the AppleID is yours and you control it. You cannot delete an AppleID you cannot login to.

So you will need to use account recovery -> How to use account recovery when you can’t reset your Apple ID password - Apple Support or contact Apple support (link is in that support page) to regain control of your account.

Start with If you think your Apple ID has been compromised - Apple Support

Then see Understand and control the personal information that you store with Apple - Apple Support
