My assessment wasn't too bad actually - I was very lucky that I got someone who appeared rather human. Got a good vibe off her and she tried to put me at ease. Like when I was talking about the voices saying bad stuff about people I don't know, she asked whether they were saying anything about her. So I said the voices were saying that she and my CPN (community psychiatric nurse) were conspiring to kill me
She then tried to reassure me briefly that she's not out to kill me
She was a bit daft in some respects though - clearly hadn't read up on my condition at all to see how it might affect me or what it might involve. Like for PIP, there's a question about managing money. So I started explaining that in hypomanic episodes, I can't control my spending at all and she looked bemused and shocked and was like "so are you diagnosed with bipolar?" Like if she'd bothered to Google my mental health condition, she'd know that it encompasses symptoms of schizophrenia and bipolar
Ngl, it is a very gruelling process to navigate and they don't really give you sufficient time to apply, or to appeal - a month for both those things. Like, the DWP must know that most disabled people won't be able to gather all the evidence, get help filling in the form, and apply/appeal within that time
I believe something like 50% of cases that are appealed, the decision is overturned in their favour and they are (eventually) made a PIP award. I was very lucky to not have to appeal at all, was bracing myself to.
My advice would be to go for it but prepare as much as you can in advance so that as soon as you get the form, you can get going on it quite easily. Get family and/or a local disability charity to help you fill in the form.
@Pathway sent me a really helpful booklet - can PM it to you if that would help
Regarding the brain fog thing, I make super-detailed notes to so that my notes can do my remembering for me. But that takes time and energy that I don't have, so it's not an ideal system
