Laura,
So sorry for all your anxiety and I agree with all of the above advice on getting anti-anx meds--there WILL be someone out there to do that for you.
In the meantime, breathe deep, visualise a lovely place that someday you'll be at, in good health, and know that worrying won't make any difference to the outcome--I know, easier said than done, but it IS true!
And I understand about your daughter--I have taught lots of kids with cystic fibrosis and taken them on residentials, and I know that the constant antibiotics, nebulisers, physio, pancreatic enzyme food drugs regime is exhausting, and that the disease is life-limiting and you want the best of that life for your babe.
Thinking of you,
Brenda
