Reducing my work hours using PIP

Hi all, applied for pip at the end on March, had my assessment end of April and I have my fingers crossed for a positive outcome as my condition is getting worse and I need to work a 40 hour week to pay the bills, I'm suffering with osteoarthritis and type 2 diabetes, I'm hoping to be able to reduce my working hours, getting up and ready for work every day is a painful experience and I just need more time for my body to recover and help myself with physio etc
