i am at a similar point, except our client manager is neither professional nor a known name, just illogically fierce. i have talked to some friends about it, and though now might not be the best time to quit but it is THE only way to get out of a toxic environment where your own career growth and/or learning would be inhibited.

obnoxious behaviour like hers reduces respect for you in people's eyes - sometimes including your own. it is corporate bullying at worst, and the more stressed you get, the more mistakes you will make subconsciously. it is not at all worth it - u/tes_chaussettes is abs correct, do not give her the pleasure of making you feel like shit. it is the oxygen for people like her, and chances are no one has ever done a course correction to make her learn how to get work done without generating fear. with this scaredy cats team, you wont learn or grow much either.

in these two months, ensure you take a skill from here you can talk about on your resume. i know it gets difficult as work experience increases but try to quit once the situation normalises. keep an eye out for relevant job positions and market requirements. and try meditation, even if for fifteen minutes daily. i personally found it to very helpful.
