Pip

i am extremely angry I've applied for pip 11 months ago and have just received court date for appeal at my assessment the person was nurse who pulled me in with her I was a nurse. My son was suicidal at the time yet she said my mood was good !!!!!!! I requested copy of report and she gave me 0 points for everything  and put on every page nurse works on busy medical ward !!!!! Tell me why I should get penalised for working!!!!!! Sorry I don't want my children to grow up on benefits !!!!
 What kind of questions will I be asked at appeal I have never been near a court of law !!!!!!!
