I have a female friend that I sort of weirdly just became “friends” with out of the blue through pregnancy?

We’re not close but she messages me every single day basically just to complain, about, well...everything 🙃

She never asks me how I am, never starts conversations like a normal friendship”hey, how are you” it’s always bam, straight into why she’s upset, hates something or having a crisis that isn’t a crisis but over dramatic basically. I do want to help her sometimes but she makes it immeasurably hard because I try to constantly give positives and upbeat things, etc and she shits it all down or blunt replies me.

She downs everything no matter how I put it and I’ve told her she needs to stop being so negative in polite ways or seek help, etc, she acts like the worlds always falling on her but most of it she’s caused. I’m getting significantly drained keeping up with advice or talking too her, I can’t confront her on how she’s being because she gets ratty and hormonal, starts playing victim when anyone tries to home truth her. What can I even do at this point?
