When I was filling in my form (ie whole book) for Disability Allowance, I got help from a local charity. I'm not saying this is an option for you, just that they don't exactly make it easy over here either.

And when I had my assessment after a year it was decided I would be able to return to some sort of work with assistance.
A fact I was informed of three months later - a few days before a payment was due. Which lead to stress and borrowing and having to sign on as unemployed immediately, and only elegible for unemployment allowance if I proved I was actively seeking work and agreed to take any reasonable offer of employment. The Job Centre was "currently recruiting" a Disability Advisor at the time.

My situation was nowhere near as grim as yours. But my experience of the benefits system is if you're crazy enough to want to stay in it, you're probably too unstable to work anyway.

Good luck with your hoop-jumping to find work, while still being treated like a scrounger.
