Liz,
Please take comfort in knowing that many people around the world are praying for Paul to be found. Not everyone who reads the boards replies so add them to the list of OCF forum members who have responded publicly and privately, the local people and now people in your region and nationally.
Your reactions and feelings are perfectly normal. Approaching the 29th would be difficult by itself.
From what you have written before, it would seem that
Robin would expect you to continue calling on your inner strength until Paul is found and then deal with whatever situation arises. For now you can only trust that the searchers are diligent and that whatever the outcome, some good will result.
