Karen Langford, 71, from Somerset, was diagnosed with rheumatoid arthritis eight years ago.
All her major joints become inflamed and extremely painful.
And then, she needs more help to manage daily life.
“When I get a flare-up, I feel like I have flu," Mrs Langford says.
"I can’t walk, use my hands or do basic tasks like personal care or house work."
Mrs Langford says she was advised to apply for PIP a year after her diagnosis.
The application involved her completing a written form and an in-person assessment with a nurse.
Mrs Langford qualified for the basic rate of PIP, about £65 per week, which she says she spends on reflexology treatment and help with cleaning and other household tasks when needed.
It also helps with hospital parking charges and journeys to the pharmacy to collect her medication.
“This isn't about me going for a day at the beach and buying everyone an ice cream," Mrs Langford says.
"It’s about me maintaining independence, not being a burden on my family and keeping my dignity.
"PIP has enhanced my quality of life.
"It means I don’t have to struggle and I don’t have to constantly ask for help from my busy family."
Mrs Langford says her condition has gradually deteriorated over the years.
And on some days in the past 18 months, she has been unable get out of bed.
"The government is completely out of touch with people who have chronic illnesses, like me, and how we exist on a daily basis," Mrs Langford says.
"Why pick on people like us, who will be really impacted if they stop this benefit?
"I have worked hard and never claimed anything before."
