PIP assessment - and I didn't send in the form ....

Just before Christmas, I was persuaded by my support worker to apply for a PIP.  Having been sent the forms, I proceeded to try to complete them.

I had a bit of difficulty, looked on websites for pointers as to how to fill them in.  Now I know I have problems.  But generally I seem to be able to run my life if I don't have interference.  Where I have biggest problems is forgetfulness, a 'hoarding' and 'untidyness' problem, inadvertantly upsetting others, and problems with missing my footing, knocking into things (and having shop items 'jump' off shelves frequently when I pass!) and falling over once or twice every couple of months.  I don't usually hurt myself when I fall over, probably as a result of learning how to fall. I also have problems with cooking (I don't do it, apart from boil an egg or put something in the microwave, usually eating cold food).

So I did not send the forms in at all, thinking I would not be eligible and not wanting to waste my time.  However, I have now been sent an appointment with Capita for next week.  My support worker is willing to accompany me.  But what exactly do I say?  It is not that the money would not be useful, it is that I do not want to put myself through all the stress involved with my time and then be refused when that is what I think will happen anyway (from other posts on PIP assessments).

And has anyone else just been invited 'out of the blue' having been sent the forms but not sent them off?  And should I take the (unsent) answers/evidence with me to help me or would this not help at all?
