... and also a reminder to others not to try and complete the AA form without some help. The relevant government agency will send out someone to help you. You can also go to Age UK, CAB etc.
It is some years since I was involved in work as a benefits advisor, but I lost count of the number of times I was sent out to complete forms and successfully get AA for people who had applied without help and been turned down. I used to describe the form as like a set of exercises that you had to get exactly right; there were certain words that needed to be used, certain key questions, key concepts, that needed to be answered in an absolutely 'correct' way to get AA.
