If you're looking to delete your Facebook account but have lost access to both your email and password, the process can be a bit tricky. Here are some steps to consider:

1. Contact Facebook Support: Try reaching out to Facebook support to explain your situation. They may ask for alternative verification methods to confirm your identity.
2. Use Trusted Contacts: If you've set up Trusted Contacts on Facebook, they may be able to help you recover access to your account.
3. Try Account Recovery: Facebook offers an account recovery process that can help you regain access to your account, even if you've lost your login credentials.
4. Report the Issue: If all else fails, report the issue to Facebook and explain that you no longer have access to your email or password.

It's important to note that deleting your Facebook account permanently can have consequences, so make sure this is the right decision for you.
