Hi Lauren,
Presumably you explained that eg breathlessness caused difficulties as to why you couldn't do various PIP descriptor activities? Do you have a doctor's report confirming the diagnosis?
PIP is about what you can/can't do rather than having a label of say 'asthma' etc. However having a GP report to confirm a diagnosis will add weight to your application. So if you have the report or can get one, send it in ASAP to support your claim. Or you can simply write a letter confirming your diagnosis. I am sure it won't be too late as DWP have big delays at present, but don't wait too long!
I hope this helps.
