No one said you had to ungoogle your life all at once. Take steps. Switch your browser to Fx or something else. Pick up a new email address with low fees with calendar & contact sync over CalDAV/CardDAV & keep both emails in use while slowly converting some over to the new address. Use LiberOffice or Etherpad on new documents. Use UnifiedPush on Android to handle notifications without send everything through Google. Install F-Droid & migrate to open alternatives. Eventually, you’d find Aurora store is just used for a handful of apps like your bank & everything else is in your browser or uses an open protocol so F-Droid apps work fine.
