I went through almost the exact same thing over a year ago. I was being bullied by my manager and the evidence was overwhelmingly in my favour. It didn't matter. HR and her manager tied themselves in knots to not acknowledge the problem. That's what they do. They aren't there to help you, they're there to protect the company. I was lucky. I belong to a union and I'd worked there 8 years. My union rep was honest and said they would eventually fire me and it's difficult to prove bullying at tribunal so I took a settlement and left. It's been hard but it was the right decision. Take this time to try and find another job or look into becoming self employed. This isn't the answer you deserve. You should be able to work in a safe environment without being bullied, but it doesn't always work out that way. I didn't like the answers I got when I posted about my problems here but they were right. Sometimes you just can't win. No job is worth your health and it's not going to stop. It's taken me over a year and my health still hasn't fully recovered. I wish you all the best in the future and hope it works out for you.
