Apocalypse Space: I've Finally Gone Crazy

[No romance + apocalypse + reborn + storage space + natural disasters + zombies + hoarding supplies + strong female lead + villainess + ruthless and decisive] Zhang Lingxiu lived a miserable, timid life in her previous life. In an apocalypse crowded with powerful people, she was little more than background scenery, and even her death was pathetic. Given another chance at life, she resolves to live boldly and confidently. And finally... she goes completely crazy.

But somehow, after going crazy, she seems to be living a lot better.

The heroine of this book has whatever morals suit her, no feelings, and a selfish streak. She's occasionally kind and frequently unhinged. There's no plot, just heartfelt sincerity.
