HHELP!! Depression due to toxic work environment

I feel I may be getting terminated and I have to figure out how to approach this...please help! I’m seeing a psychiatrist tomorrow. Here is the thing, I have been working at my job 8 years. My extra patient supervision retired in 2015. I worked solo taking on the workload of more than one person for over a year. I never once got written up. In 2016, a new supervisor was hired from within the company. She seemed okay at first. She then wrote me up 2 months into her new position, 2 days before my vacation with a lot of things that were petty, and she even stated how I’m “mad because I didn’t get her job” ..I signed because it being close to my vacation, i was upset I continued to be bullied by this new supervisor who clearly had it out for me. She send me very demanding and unprofessional emails. I got written up yet again by her supervisor a year or so later because of an audit that had a bad score. I am responsible for the files, and so I took responsibility. I was transferred to another office. There are 2 girls there who have been very nasty but I ignore them..j had a situation where one of the girls called me a ***** in Spanish. I reported her, and my supervisor talked to the two girls she is in cahoots with and they lied which my supervisor believed and didn’t take
sides. Due to the toxic work environment, I have been unable to concentrate and work to my full potential and I feel I have been treated unfairly. My supervisor has reminded me time and again that if I’m written up again, I’ll be terminated. I have been doing my best under the circumstances, and yes I have let a couple things slip and made a couple mistakes but as soon as I am told something I correct it. There are a couple mistakes, that I was unable to correct that was thrown in my face today and my supervisor said she is writing me up, and how I have the smallest workload of anyone and I don’t have the skills for the job. I was improperly trained which I tried to bring to her attention, and she retorted a nasty comment insinuating that I was making excuses. In addition, she is nasty, rude, and indifferent. My former supervisor made some very demeaning comments on an email and my supervisor was copied on it and nothing was done.

I need advice which approach I should take when I see my psychiatrist tomorrow? It’s a first appointment but I can’t sit around and do nothing.

I don’t have any advice but wanted to offer my support and wish you luck at your pdoc appointment. I’ve worked in toxic work environments before and it’s rough and takes a toll on you. Is there any possibility of you taking another job?

probably not. I’ll look into it, but it’s doubtful. My best bet is to look for a new job. I’m taking a day or two off and I’m applying for a new job..

It's cliché, but in such situations...
Document, document, document!
Save all the emails and make memos of all the incidents, encounters and meetings.
"HR" is not your friend. Ultimately, their job is to protect the company.
Consider talking to an attorney specializing in labor issues ("labor attorney" or "employment attorney").

Personally, I think it best you leave that environment. Some sort of counselor with labor/employment-issues experience should have a good idea how best to make the transition out.
May this all turn out in your favor.

I’m thinking of you
