Pip telephone assessment question

Hi I just wanted to find out if anyone else has been in a similar situation as me and how they dealt with it please?
Il explain as quickly as possible as I do tend to rant or ramble on sorry in advance if I do!
I had been getting dla then pip for over 10 years and this award ended at beginning of the year so had to have a telephone assessment which I had in February. I got decision back in 12 days saying I'd been awarded nowt no points for either daily living or mobility which in itself is so wrong to me because I'm much much worse affected now than I was 10 years ago by my lungs etc so it makes zero sense that I'd get less or no pip today! But anyway my issue is the decision maker explains how she made her decision based on report from the assessment and she goes through all the questions and answers I gave but the problem is I answered the questions VERY differently from what is written on the letter? Literally everything I spent nearly 3 hours on phone explaining to the assessment lady is not included in the report apparently?! I have tortured myself for months now have relapsed several times with my self harm I feel so ashamed of myself but it's almost like I'm being called a liar? Or they are trying to make me crazier than I already am! I just don't understand how or why she has done this? One example il give is I told her I struggle to breathe just walking from my front door to the taxi they have to help me to the car it's about 3 metres? She said I can walk up to 200 metres unaided??? And that's the kind of thing that's happened all the way through the decision letter :-( I told her specifically about things I can't begin to do and she's said I have no problems doing any of them! Anyway sorry I have had all this building up in my head for so long and nobody to talk to about it all! I really just need to know if those assessments are recorded? If I can essentially prove they haven't been honest? I mean it's very simple either the assessment lady lied and left out 90% of the information? Or the decision makers at dwp ignored all of it? There's no other excuse I can see? I mean I've done the MR as I basically have no choice I literally have missed 3 important hospital appointments in the last month alone because I can't afford to go there and back :-( I just worry this will keep happening to others too I mean I've been in some very dark places since that decision! And it scares me! My mental health is worse than ever most days just sit in my bed unable to stop obsessing over this situation and arguing with them in my head like a loon!! Even out loud? I'm literally arguing to myself out loud it's so pathetic! But if anyone has actually made it through this long message and has had a similar experience and knows about what copies of records calls etc I can request so I can see if the report is wrong or the decision maker? Or how I can take this further so it stops happening? That would be amazing! Sorry again for the rant it's just so much information and so much has happened I don't want to miss things out as it won't make sense? Take care peeps and stay safe xx
