Please Help with Advice for mandatory reconsideration

hi can someone please help me I have had my pip review and they have reduced my mobility point from 12 to 10 so I will lose my vehicle.

they have stated there is insufficient evidence that you would experience overwhelming distress to undertake a familiar journey.

I told them in only leave the house to pick my son up from school or dentist doctor and my routine 3 monthly Hosital check up appointments.

they never asked me if I can safely drive to these appointments without someone with me they only asked about picking my son up from school which 90 percent of the time I need my daughter to accompany me or if she’s not available my next door neighbour will help me none of this was asked and I forgot to mention this.

they have agreed I cannot use any public transport or taxis due to one of my illnesses being severe anxiety.

so without my mobility vechile I am completely housebound as all my other family live back in Scotland and I am in the north east of England to be near my son.

I live alone apart from when my son is with me or my daughter is here as she is 22 and lives with her mother.

I don’t know what I have to do or say for the mandatory reconsideration and I have nobody to help me with this so if anyone can please help that would be very much appreciated.
