Woowoo,
I am glad you feel like you can talk about it all here. It does sound like this is creating problems for you in your life.

You said it was 8 weeks before she had to fly again. this would give you time to go and talk to a professional and perhaps be better able to sort out your feelings about all of this. If with the help of a professional and perhaps some medication the fears subsided then it would seem likely that it was an OCD issue.

Does this seem reasonable?
