I have been degoogled for a lifetime.

You really do not need anything google, except of course AOSP, The Android Open Source Project.

Where there is a will there is a way.

Buy a cheap 5 year old phone you can install a Lineage or E.foundation operating system.

https://doc.e.foundation/devices

Either that or learn to use ADB (Android Debug Bridge) to remove all those unnecessary apps on your current phone.
You dont need most google stuff on your phone and they are not a required, in fact you do not need 75% of the bloatware on your phone, there are better open source alternatives.

Change your email provider. I use both protonmail and Tutanota email with very good apps. Proton also provide an excellent free protonvpn.

Create a email redirect from Gmail to either of the above until you have notified all your contacts of your email change. Dont forget your bank, insurance and utility providers and social media if you use them, etc.

live a stress free life, free of interruptions and abuse of your personal data.
