there are a few different websites I have used, also facebook groups are fantastic.
This forum is quiet and not many people post anymore or keep coming back to it, but reading through some old posts can be quite informative. Also if this person did come on here, I would try to get on more often to hopefully offer some support.
A busier forum is www.cftrust.org.uk. It's is the UK based registered trust for CF. They have sections for adults, teens, parents and partners. Even though it's UK based there are a couple of members not from the UK, and while US advice not be in great supply on there, it's a great place for support, and is a lot busier.
Hope this helps
