PIP Telephone assesment on 11th Aug. I'm genuinely scared.

I was awarded PIP in 2020 after major surgery. Mostly recovered from that. They threw me ou after 2 years. Now my health is more complicated and mental health worse than ever.
I have my tel assesment next week and I need advice on what to say, not to say, how to be with them. Last one was so scary I just wanted it to be over.
Succinct advice greatly received.
I am Autistic
Complex PTSD
LOng Covid
Lichen Sclerosis
Mixed Anxiety & Depression
Permanently traumatised bowel after major surgery and resections.

Thanks for your help, kind people.
I want to feel prepared, safe, able to speak my truth.

Dear AL, I too am autistic, so I hope you will find my tips useful. Yes it is not long now.
However please try and find someone who can be on the call with you. If they are autistic like you, as my supporter was, maybe they will 'get' how you are reacting during the call. But any supporter is good as it tends to put the assessor on warning not to mess with you. They can be dialled in to a three-way call, they don't have to come to your home.
Secondly please practise whatever means you have available to make your own private recording of the call. Then you can do so with minimum distraction on the day. Having your own recording is a very important insurance policy against any later attempts by them to lie about what was said.
Thinking of you AL, with best wishes for it to go OK,
Denby

Ah, thanks for that David, I admit I judged only by my own experience where the 3-way went fine. Makes own recording even more important unfortunately.
