Pip assessment yesterday

H new here I applied for pip in early July and received a couple of texts nothing else until yesterday I was phoned by a pip assessor out of the blue saying she received an in depth report from my go and just needed to ask a few questions and then she'd send the report off first question is this normal practice? I was taken totally unaware but answered all the questions she asked I have to say she was very understanding and helpful but keep asking same question about going out on my own and I said I wouldn't go anywhere without someone with me but she asked if through some situation I was in town on my own how would I react i explained I'd have a panic attack and sit down then phone someone to take me home I felt it was a trick question and she kept asking it. then she keep asking a few times that I could go out on as long as I had support i.e someone with me, would I be marked down for this? I found the whole thing unexpected and truatmatisiing esp afterwards as I've had mental health now expecting a negative decision because there was no arrangement for a full assessment just a 20 min phone call out of blue
