Moving away from Gmail was easy for me. Get a new address at a reliable provider or self host. And then you can use Gmail's own Mail-forwarding functionality to forward everything to your new mail address, and theres also an option to delete the copy at gmail.
Whenever you have time, set the new address at your accounts. And after a year or two you have changed all accounts and can delete your gmail address.
A slow change is better than no change.
