You've never worked in mental health, have you, @Polishedshoesalways ?
Yes, work is good for you. My DS loves his job. But he will never be able to work full time because his myriad health conditions, for which no cure exists at present, do not permit it. He has been very lucky to get a job that suits him, with an understanding employer who makes allowances. Such jobs are like hens' teeth
For people who are worse off than he is in terms of their MH - the UK's mental health services are so bad that they cannot get someone to a point in their recovery where they can take a job, hold a job and benefit from a job. Waiting lists are huge. Thresholds for access to services are very high.
But you know all this, you just don't care.
