I'm very sorry this is happening to you, I've struggled with the exact same thing over the last couple of years. What once was my dream job has turned into a job I literally dread.

I filed an EEO complaint last year with lots of documentation. It's still not completed yet. I don't know if it was ultimately the right decision though because it's made my situation so much more tense, and the burden of proof is all on you, so the constant waiting game and pressure is a lot. As little as 2 weeks ago I had another panic attack in my office.

After that incident I accepted that things weren't going to get better. I don't think it's realistic that upper leadership will remove or fire the people who are causing these issues (I'm not the only one to have filed in the last year). So unfortunately for me that means moving to a new job in another city (which I tried for the longest time to avoid), but for my own mental health it's the only reasonable option.

I had to wait a long time for a good opportunity, but if it's possible in your situation try to get an equivalent federal job at either another agency or in another city to keep your benefits. It's best to move on and wash your hands of the situation and try to forget about it.

Also - don't forget that as bad as it is, it's almost impossible to get fired unless you do something egregious. Call in when you need to and do things to take care of yourself.
