MAG Employee, Tired of Abusive Manager, Don't Know what to do anymore

Hey everyone, I dont really have any place to go but so I thought I would just talk to a bunch of strangers who might understand me or the working conditions in the OPS, specifically in MAG. I have a perm position as one of the worst entry level jobs in the entire OPS, in the courts. I have recently left a temp position from Toronto to a Perm position in West Region. My current supervisor is an abusive manipulative person. Some context, today marks 33 days of me working there and she has reached out to HR and my old supervisor complaining about me. Part of my role entails being through into court of office and often each day is different. Leading up to her going to my old manager, she keeps calling me into office and accusing me of things that are just simply not true and outlandish. She has told me that I am using the work laptop "for none training purposes" which is a lie because I can't really do anything besides check emails and use FORTE, she has accused me of drinking coffee in court which I also do not do as I am not an idiot and know that in front of the public and judiciary I cant do any of that, she has accused me of coming in late and she micromanages me on every single minute I am here. Then upon hire she told me that I would be in court 3 days and office 2 day, then every hour she changes her mind, she has completely lied and said that I have pulled out from trainings and has even had the audacity to ask me, "why did you take this job" and "this is not Toronto, I dont know how you do things there". Every single coworker of mine talks shit about her and how shes controlling and micromanagy but once I said that this place is a little toxic and apparently because I am the only POC at the workplace they all want to go and tell her. Yes I made one or two wrong judgments but I feel extremely depressed, s*icidal, alone, frustrated and anxious around my supervisor. I literally feel nervous and anxious when she messages me on teams or randomly calls me.

Its worth noting that she has horrid people skills, shes extremely rude and starts conversations where she is accusing you first and then expects you to not even reply or defend yourself. She told my previous manager that I always say "okay or hmm hmm" when she is talking to me. like what should i say when shes genuinely making accusations about me and making it difficult for me to do work?? Every single place she puts me in, she keeps moving me and everything is inconsistent. My old supervisor told me in confidentiality that she checks when i come in and leave, she constantly has issues with me and that she is reaching out to HR. its been 33 days, 34 tomorrow and I have not slept a single night in peace, I am scared, alone and have to hold everything in when she is unhinged and abusive and I cant even be myself or breathe in peace. And my disgusting co workers, they have made things even worse for me by talking shit and making up stories behind my back. I only asked my "union rep" questions about my position and who to speak to and that person told my supervisor.

I feel alone, su*icidal and I literally feel alone and its bringing back all of my traumas from childhood and after having my previous supervisor who was so caring and supportive, I feel so alone being the only Person of Colour surrounded by people who hate me for existing and then her. I would own up to anything that I genuinely did wrong but I cant talk to union, she has told her manager already and she is orchestrating all of this shit behind my back and I am scared she will go to HR and create a case on me with false grounds. I feel hopeless and alone, I am so anxious to go tomorrow to see what she will do to me tomorrow, as if my personal life isnt alone and hard enough, only for $29 which isnt even livable wage. I dont know what to do besides cry anymore.
