Pip refused after second assessment

Hi I am doing this on behalf of my 21 year old daughter . She was diagnosed with Asperger syndrome when she ways 8 and since then also anxiety ,depression and OCD. 

She was awarded pip enhanced when she was 16 she has recently been re assessed and awarded 0 points .

She asked them to look at it again and the same response zero points. I have a copy of her mandatory reconsideration letter received   today . 

She is at her whits end today and has developed a skin condition now due to stress . She lives independently near me for support and now the concern is that she will now lose her home too on top of this 

please please can anyone give me some advice so I may try help her
