PIP appeal help

My daughter has ADHD applied for pip scored no points . Her consultant said we should appeal so we did waited 12 months had the appeal other day which was very intense and formal . Received letter today saying she was refused  but scored her 5 points for daily living component and 4 points for notability component  absolutely disgusted had 10 years of coping with problems  due to her ADHD .  And find out today a relative who is 2 years behind in education and not diagnosed with anything just has some problems gets awarded DLA  the pip system is a joke should let the dwp have my daughter for a day . She's now 19 but still hard work day to day don't know what to do now wouldn't like to go to next appeal process my daughter would not cope . It's unfair how you get treated in this country .
