Welcome @CoffeeChris. That sounds like a really tough situation. You might try a good DBT therapist and group to help learn some relaxation and coping skills. Not that YOU are the problem, clearly you are not, it’s your work environment, but you might learn some techniques on how to just manage what you are able to manage. That’s all I can think of off the top of my head, sorry, but hopefully others here can give you some extra tips on how to proceed.
Good that you’re here and talking about the problem, hopefully that can bring at least a little relief. I think if you scan through the forum, you’ll see other posts by people who also have a lot of job-related stress.
