Mental health and physical element of the uc50 questionnaire

My daughter suffers with learning disabilities, anxiety and depression. I am currently filling in her uc50 form. She has received the enhanced rate of PIP with an ongoing award from the age of 16 with one review where she was re awarded it at this rate, (she is now 26) My concern is that her moving around element of pip is based on her mental ability to process dangers and extreme anxiety, when the uc50 physical portion of the claim could potentially effect her current pip claim if I say she has no physical disabilities. However, her mental health causes physical symptoms such as hyperventilating, heart palpitations, dizziness, nausea vomiting and diarrhoea among others. Her learning disability causes her to panic and be hysterical which can be deemed as socially unacceptable behaviour for a grown woman. With this in mind Would I say not applicable next to the yes, no and it varies boxes .. not tick any and explain how her anxiety effects her physically and this is why she can’t reliably, safely and repeatedly perform the physical elements?
Any advice would be appreciated
