Is it ever a good idea to tell your employer about your poor mental health

[gabsdot45]

I currently work in a job where I work alone all the time . It's a door to door type thing but I'm not selling anything and It's a government job so I can't really be fired however badly I perform. I've been doing this job for 7 years and I'm really fed up of it and have been looking for a new job for months now but with no luck.
I'm also starting to slip into depression. Not job related, I think it's probable the menopause. I've had a particularly bad week this week. This evening I drove to the area I was due to work in and I couldn't get out of the car. I felt as if i'd have a panic attack.
Tomorrow I'm meeting my supervisor for my 6 monthly review mtg.
Should I tell her how I've been feeling. She's about 10 years older that me so might be sympathetic about the menopause thing but she's also under pressure from her higher-ups to get better results.
Is it ever a good idea to tell your employer about poor mental health

I worked in civil service before, my job sounds similar to yours. When we had this HR "initiative" called "declare your disability" which generously included being considered disabled even if you have been on antidepressants, and I've been on them for 20 years, I thought "no way, fuck you. It's none of your business". Since my sick leave was never related to mental health issue I never told them.

However, when the job changed and became more stressful, I warned them of my limits. That helped.

So, the gist of what I'm saying is: if your performance is not affected, and you haven't taken any sick leave due to MH, then don't tell them. You just hate your job. A lot of people do. But if you fear the job will make it worse, and you would benefit from some adjustments, then speak about it, but not in terms of mental health, but of menopause.

It's too late for OP now, but, in case other people reading this are wondering the same thing, I would like to say that my manager is just about the only person I talk to about it. A lot of my issue is related to work though, and I was forced to talk to her a bit when I started crying at work one day. She is incredibly supportive, positively encourages me to take time off when things are too much ( I don't), offers to change working patterns etc if that will help (not feasible due to childcare etc) and is trying to refer me to other sources of support within the organisation. I am very lucky. I realise I am very hard to help, very reluctant to talk about it, refuse all her sensible suggestions or take a lot of persuading, but she has supported me through the last 6 months.
