ADP review, help deciding best course of action

Hi, Sorry to ask advice on this but one of the reasons I qualify for ADP (Scottish PIP) is that I'm not capable of making financial decisions, or even ordinary decisions a lot of time due to my mental health problems.

Last time I had a review I was not at all well, was not very informed and just ticked 'no change' and returned it. I later read that this risked me losing my benefit but I was lucky and did not (I receive the higher award for the first section and no award for the second section).

I've got a new review coming up and I'd seen the Benefits and Work published figures for how risky it is to choose 'no change' just on the basis of not getting renewed. And I also fear the proposed new rules that make only higher scoring applicants get benefits at all.

The truth is my condition is changed, for the worse I belief. I also think they were wrong originally in not awarding me anything for the ability to plan a journey section and scored me very low on the budgeting section but I did not have the resources to challenge it.

I've spent the last week giving a really detailed rundown of my abilities/disabilities but I look at the information I submitted last time and feel ongoing bewilderment at how they could read all that yet still not give me any points.

I'm feeling torn between opening raw places in me by resubmitting my information just to be knocked back and taking the risk of just ticking 'no change' again. I'm afraid my brain is turning to mush over all of this. Can anyone help me with offering their perspective on this please?
