Im rly sad for her, it starts with the marriage problem(that one was actually her fault) then her father cancer, now her career is falling apart and to add ppl talking behind her back making her a "bitch".
Some of that could be avoided for sure, just pay more attention to you marriage and talk about your problems, your husband was there for you, he looks like a kind man and then at work ppl make mistaked, we are only humans, don't be mean.
I can see her completly breaking in upcoming chapters, she gonna be demoted in her work somehow, i can also see her terapist being into her and trying sth dirty, it might happen that she gonna have sex with some guy( would say terapist or her boss to get promotion when she loses all hope?)
I hope it finishes when MC get to know about all her problems and gonna help her and they get together so the conclusion gonna be to share your problems with ur partner, don't try to fight alone.
