My attempt to leave Google Drive, need a littl…

There’s just one thing nagging me: I used to keep sensitive documents on my Drive but I’ve since deleted them. I know that doesn’t guarantee that Google actually deleted them at all so here’s my question (followed by misc thoughts below): is there anything more I can do here to increase my peace of mind? I considered overwriting documents with nonsense, but they have version control that goes back to when the file was first created.Google is too convenient and the alternatives, attractive as they are, all seem to take some setup. The whole process of learning about all the software I need, what they do and how to use them is, admittedly, boring and tedious even if I think I want to do it. In this particular situation, I think encrypting password-protected zips before uploading them to cloud is the right compromise for me but it’s still a hassle (I downloaded Cryptomator 2 months ago and haven’t touched it).My current mentality is “fuck Google completely” but it’s insanely hard to leave. Speaking as a young person who has used Google’s services since elementary, it’s almost like my generation was born into the ecosystem – I must’ve been with Google for over 10 years by the time I discovered /r/privacy which horrifies me.
