Life is miserable after my company went under and I joined an SME

An accountant who graduated from a commercial high school and is 12 years older than me is giving me dirty looks and acting like a gatekeeper.
It's intense.... I'm actually her superior since I'm an experienced hire, lol.
It's a mess. When I ask her something about work, she just says, "It's written in the documents," whew!
Sigh, hahaha.
Even the other older guys can't really mess with her.
Scary.
Ah, should I just write my resignation letter here too?
