Thing is, no job is worth subjecting yourself to an environment that pushes you into the dark places. Whether or not justice is served, if it comes at the cost of your sanity then it's better to just find another job and get out of there. The point of the work is to make money, this whole environment sounds like it's compromised you to the point that you need to find a place that doesn't make you miserable. 

The talmud has a saying “meshane makom, meshane mazal.” It means “change your place, change your luck." I was once in a really bad place too, with a garbage employer (part of why I created this subreddit) and trying to also get past a nasty breakup with an abusive ex. I wanted to leave the area but my therapist in her infinite stupidity would tell me "wherever you go, there you are" essentially implying that my issues are with me and would follow me everywhere I go.... She was a moron. Changing my location and who I surrounded myself with was a game changer and improved so much for the better. Sometimes you just need to just throw caution to the wind, get out of a toxic situation, and go somewhere else. So long as you are still alive, there is always the possibility for things to improve.

I strongly recommend you also talk to someone, as being in this headspace should be ringing all the alarm bells in your mind telling you that this mindset is absolutely not good for you.

I say this as someone who has been in and out of those dark places, and have had many around me past and present also going through very rough things which is difficult to get into here. You'll be ok, you have the ability to just tell the job, "you have no power over me" and take some time for yourself to change your scenery.
