Does the PIP assessment over ride the form

I'm changing over from DLA to (hopefully) PIP.
Today I had a home assessment and even though the assessor seemed nice, due to my anxiety ( I have severe generlised anxiety disorder, inc OCD, social anxiety and depression) as well as physical issues, i'm worried I've forgotten to mention things in the assessment that I have put on the form. For example: with regards to eating, I told him I need encouraging to eat and have low appetite, my partner cuts my food & I suffer nausea He asked me if I was hungry what would I do, I said ask my partner, I forgot to say that due to pain I will sometimes not eat even though I may be hungry - I have put this on the form though.
And there is a few other things I feel I should have qualified, do they take both the form and assessment into account, or if something is not mentioned in both is it disregarded?. I struggled a lot because I was told about "we'll come to that bit later" then i'm not sure if it was said again. Thanks
