https://www.mangago.me/read-manga/sweet_home/ it’s here on mangago, but I recommend reading it on webtoon because it’s free, probably better quality, and you support the author!
if you want something more gore-y
https://www.mangago.me/read-manga/pygmalion/
also here is a tag for apocalyptic manga/hwas https://www.mangago.me/tag/apocalypse

I’ve already read sweet home but thanks for the rest of the recommendations (づ￣▽￣)づ
