Hi Gaynor, the PIP guides on this website would help you fill out the form.
It would all depend on the descriptors in the form and how well and often for example you can get dressed everyday. Breathlessness would come into play a lot, and this would for example slow you down a lot when washing, walking, having a conversation, even eating, and that would be one aspect.
If there are help groups for IPF or the charity website, I'm sure there would be support there to help fill out your PIP form correctly as it can be a minefield struggling alone.
Good luck
