video assessment following change in circumstances form

Hello,

I was awarded standard daily and mobility following a tribunal nearly 3 years after applying for PIP. My circumstances had changed with a worsening of symptoms and further diagnosis of two chronic and progressive conditions. I provided a lot of detail of these before my tribunal but was told in the tribunal they would only consider information given when I first applied.

Citizens Advice told me if I was awarded PIP, which I was, I could submit a change in circumstances form for new or worsening symptoms, which I did. When I phoned up to do this I said I couldn't go through any kind of assessment again as it was so stressful and made me very ill, and was told I wouldn't need to, that I would just submit the form and ask them to refer to the additional evidence detailing my worsening symptoms and further diagnosis. So I did. And now I've received a message to say I will have a video assessment in a week and a half.

I literally have no one to be with me during this, as I only have two friends and they both live a long way away. One came to the tribunal with me but is away with work at the moment as well as being over 5 hours drive away. I have no family either, only a cousin I haven't seen for 25 years.

I really do not know what to do, and wish I had not submitted the change in circumstances because I can't cope with this situation or the process of an assessment. Especially by myself. It's just too much to cope with

Does anyone have any advice? Or experience of an assessment after a change in circumstances? I know my conditions and symptoms have worsened, and the two conditions I have since been diagnosed with will not improve and will only worsen over time. But I also know after my first assessment there were things in there that I hadn't even said and a lot of assumptions that were untrue.
