Had PIP Medical Review mobility reduced

I was awarded enhanced mobility in 2016 I had it awarded in 1987 after being disabled out of HM Services with New Built legs surgical steel, (which I get considerable pain from) the DLA was indefinate, I was awarded Mobility 2016 for Physical injuries and due to my auditory hallucinations which never go, I got 4 points for promting for unfamiliar journeys nothing has changed here or ever will, my auditorys are permanent, and nothing will change, so if it was ok in 2016 for higher rate it should be so now. Silverina a person on this site has same mental illness has me and gets higher rate mobility with no timer limit, I was disabled out of her majesty services with new built metal legs, which give me chronic pain and i cannot walk far, somedays at all, due to my legs deteriorating. This was 1987, my subsequent breakdown from IBM and diagnosis of ptsd and bi polar and schizzoaffective hallucinations is a daily lifelong illness, everyday I have to put up with it, somedays are wors thasn others, this was what got me higher rate mobility and care in 2016. And nothings changed. So yes I do qualify, my dr said even she was baffled.

I get promted all time, there are weeks and months when I cannot go out due to noises I get which fluctuate in volume, I have them all time I can deal when they are low, audible but manageable, when they rise in volume, thern I struggle, this happens frequently and is getting worse with age, also my legs are bad, osteo arthritis chronic pain, can hardly walk. I cannot do a lot when I am bad. thats why I get promted and help all time, in last ten years from 43 to 53 its become debilatating, when i cannot drive my car family drive me, I get support due to my auditorys even when there manageable, (they increase in volume, manageable volume 1-3 4 onwards becomes disfficult, 7, to 10. I cannot cope. I have been suicidal with this illness.

so explain how then?? I dont really follow, I was awarded the points in August 2016 and this was accepted, my illness has not changed. So you have really lost me and my mother also. I am 53, could you explain please as I am really not following you at all?
