Hello Time_2_drink, I've been watching your struggle sweetheart, although I haven't replied until now, I have been cheering you on.
I can relate to how devastated you are feeling about your new dx, although my lung condition is slightly different, it is still quite recent and on top of other medical conditions.
A little while ago I came across the link below, it explains PF in language that is easy for us ordinary folk to understand, and I found it reassuring when it seemed like this might be my dx, have look petal, it might help you as well.
You know you aren't alone and that we are all rooting for you, don't beat yourself up or feel daft, it's scary and we've all felt like that, but try to take comfort in that you at least will have a proper treatment plan and if you ask the right questions, some definite answers - write your questions down as you think of them and never, ever think that your questions are silly, after all this is YOUR health , not just a another caseload.
Sending you hugs, breaths (if I could and had any to spare!) And support
