ESA SECTION MENTAL HEALTH

I am in the process of completing the dreaded ESA form and would like someone to advice me so that i do not look a fool when someone reads my ESA form.
ESA is divided into "2" sections
a) Physical disabilities
b) Mental Cognitive and Intellectual
The guide advises the mental health section applies for a mental health condition,learning difficulty,a brain injury,substance misuse or dependancy problems!.The first 8 descriptors relate
to physical health only.
Am i right in assuming that descriptors
9 to 14 apply to mentalimpairment conditions only.
a)Take no 10 for awarness of everyday hazards such as crossing roads,avoiding hazards on pavements,dangers in crowded
conditions,etc which present a difficulty as a result of a physical
condition being blind hence requiring
supervision for considerable part of day.Do i include this or not.
b) Coping with change no 12. I wear highly specillised contact lenses to see
but this is limited to wear 6 hours a day
without which i am effectively blind.My active life is limited to 6 hours a day.
Changes in my daily routine needs to
be adjusted on daily basis for eg i could
not manage morning,afternoon,evening assignment in one day hence coping with changes isa problem but physical. Do i mention it here.
c)Also i have a "fistula" in my arm.Does
protection of this fistula determined as this arm being not usable.
d)As i have vision 6 hoursa day required for basics without my lens i am tecnically blind.Does this exempt me from doing work.

Please assist.
