How can I preserve some piece of text forever to the point I can't delete it no matter what I do?

Why is he even asking that you might wonder? Why so specific? Okay, so the story goes down like this:
>be me
>have mental breakdown
>in a vortex of paranoia and self-hatred delete precious novels, short stories, etc... I wrote years prior
>realise months later "oh fuck what I have done"
Hopefully now you understand.

I have a plan in mind, it currently involves:
>making a website and a series of pastebins
>using web archival tools to store it
I also plan to sell my new novel as a ebook, I have no pretensions of making any serious money out of it but behavioural economics proves that people appreciate more things they have spent money on, if people appreciate it more then chances it will preserved no matter my self-destructive urges in the future are increased.

I have also considered other less convenient and more extreme strategies:
>comments in code, warcraft 3 scenarios, minecraft worlds
>turning text into video and uploading it to youtube (and then archiving it)
>becoming a "lolcow" so those guillable obsessives at Kiwifarms archive my creations
