I've recently applied for a job and my application has been successful.
So now I have to fill in a lot of documents and one document caught my eye: the health declaration form.
On this form I'm being asked whether I've ever suffered from any of the following: "depression, anxiety, stress related illness or other mental health problems including self harm and eating disorders".

Yeah. I'm extremely uncomfortable they would ask me that sort of thing.
I suffer from depression and anxiety but considering the stigma mental illnesses carry, do you think I should put YES or NO in front of depression and anxiety?

It's quite an important job in a big company, I don't want to 1) make a bad impression right away and 2) mention on a form what I consider to be private information about my health.

What do you guys think?

Thanks in advance.
