it was weird. i pressed delete on a subfolder, i think one of the pages.off folders that i was using. and then, suddenly, nvim on windows 7 decided to delete every file in the directory. they weren't shred off the space time continuum, but just marked deleted. i had to pay $80 to get access to a software that could see them. bleh! just seeing all my work, a little over a week, was pretty heart shattering. but i remembered that long ago, a close friend said i could call them whenever i was feeling sad. i finally took them up on that offer. the first time i've ever called someone for emotional support. but it's ok. i got it back. and the site framework is better than ever. i'm gonna commit and push more often. the repo is private anyways.
