PIP mobility

Hi, I've been housebound since prior to 2016. I could not go out even then due to overall arthritic and physical weakness, diziness when standing and without either someone physically supporting me one side while I use a walking stick the other for short distances of maximum up to 20 meters, usually half that distance. Or being attendant pushed and supported in a wheelchair for further distances that I would just not be able to manage. I have to use one hand on furniture or walls to support me and prevent me falling as I potter around inside my flat. 10 paces at a time.
At my PIP in 2016 the health care professional acknowledged that I came to assessment by taxi with my daughter, in a wheelchair pushed by my daughter, where I remained breathless while seated. Also confirmed it was not pertinent to do a peak flow as I was breathless. Yet ticked the box that said can plan and follow the route of a journey unaided. Which is entirely untrue. Then contridicted the distance I was physically able to walk around inside my home. Saying I would manage 50 meters when there's a maximum of 10 meters distance overall from the furthest points.
Can I use the information on the 2016 PIP consultation report form that is written by the HCP to support my review application. I had been too anxious to go to appeal previously and was just grateful for the award I received at that time. I would appreciate any advice you may have for me.
Many Thanks

the HCP wrote on the report that I came by taxi and arrived in a wheelchair pushed by my daughter, that I was breathless whilst seated in the informal observation section. She failed to put this info in the mobility activities when I said I can't go anywhere unless I am pushed in a wheelchair. I have arthritis and a hiatus hernia and fatigue preventing me being able to self propel. I should have gone to appeal but was too anxious to do so. She made it sound as though this was a question about your mental capabilities. I am ticking the cannot follow the route of a familiar journey without another person giving me assistance. Is this the correct option as it is and has been the truth since prior to 2016. I find this all so confusing.
