It makes it all the harder when PIP questions aren't relevant to your personal situation, abilities or requirements. There's no grey areas allowed in answers either. It's like trying to explain the problems when you aren't allowed to use words.
I worked for the NHS for over 20 years in disability rehabilitation, before my disability wasn't accomodated by my employer during the pandemic. PIP has been the most dehumanising, humiliating experience of my life. It degrades me. I wish non PIP claimants understood that.
