Frustrated with mental health support
I'm having difficulties getting my workplace to take me seriously enough. I've been diagnosed with Generalised Anxiety Disorder, of which they are fully aware. It was diagnosed only recently but I've been suffering with it probably since about 2018. In 2020/21 I had a traumatic time that had nothing to do with COVID but which aggravated everything.
My workplace have been good to me generally, providing time off when I needed in the past, but I'm finding that the longer time goes on they less they seem to understand that I am not going to just be suddenly better. I used to have an office by myself, but when we relocated I was put in an open place space which I struggle to work in. I got the desk in the least bad place and it's mine, even though we are technically supposed to be hotdesking, but it isn't really enough. I've stuck it out for several months but am still struggling. When I made, what I thought, to be a quite reasonable suggestion in moving to a desk in a different room, I got a reply about getting better earphones which completely misunderstood my issue.
At this point I'm not sure what to do. If I ask my workplace for an occupational health review are they obliged to do it? I'm at a point where I feel like I need someone to mediate on my behalf. There is no formal internal HR and staff have no direct access to the external HR company.
