Oh of course I agree re mental health. It's important to look after it, but also to work with it, not against it.
I suffered from a bad case of anxiety last year for about 2-3 months. Related to menopause probably. Saw my GP about it for the first time in ages and he actually listened, referred me to talking therapies, and did ask if I wanted pills - but I said no to both of those as I've had bad experiences with them in the past. I actually didn't end up requiring anything and got through it by myself (I didn't think I would do) and luckily had savings so I could support myself whilst off work (but they won't last forever!) and do have other income, but I was much happier once I was back in work, albeit mostly WFH apart from 2 days a week in the office.
I do sometimes hear about friends DC who have mental health issues, don't want to work and don't work or have to be really supported through this. I don't doubt that a workplace or study place shouldn't help them at all, along with the requisite medical health care, but the person in question also has to help themselves, and not fall back on, I have anxiety, depression, ergo I cannot and will not work.
ND is slightly different to me, as that is far more complex and requires more care and understanding to enable people who are ND to work/study effectively. If you physically cannot work, such as DB's FIL who had a stroke and is a paraplegic then you cannot work, and he was medically retired, I think at 50 or 55.
But whereas, when I was younger, mental health was seen as, well it was recognised, and I had a bit of therapy (probably undiagnosed PTSD and PMT but severe kind), we still had to get on with it, in a sense.
We did have a form of CAHMS then but it was called something different.
I went to a child psychologist/psychotherapy centre run by the local authority/health care authority from age 14-15 to about 17 for regular therapy sessions once a week after school. Not that it did me any good as all the person there did was listen to me! It would've been far better for me to manage when I got depressed/anxious (which my DM eventually linked my severe PMT to) and I got prescribed the pill, which really helped, as it evened out my hormones! Still not sure if I have an underactive thyroid back then which I have now which was never diagnosed or tested for. Symptoms can apparently be similar to severe or normal PMT.
