My anxiety is triggered a lot when my boyfriend is not around, or when he is with certain people/doing certain things.

In July, I am house sitting for a friend for two weeks, and during this time I know I won't get to see my boyfriend very much at all, and likely won't get to spend any nights with him. And on the weekend during the time I'm house-sitting, I would have liked him to come stay with me but there is an overnight camping event that weekend that hes going to with some friends. I would normally go too, but I can't this time because of house-sitting. Tons of people go to this event, and everyone is drinking etc. The friend that my boyfriend goes with always drinks a lot and he's an idiot when hes drunk (he's engaged with two children and gets very "promiscuous" when hes drinking).

Thinking of these two weeks and the weekend is already making me nervous and anxious. And I know its going to be a really hard two weeks for me, and especially a hard weekend. I bought a new Cognitive Behaviour Therapy book that has "homework" at the end of each chapter, so I'm planning on working through at least a chapter a day during these two weeks to hopefully distract me and help with the anxiety.

I guess my question is does anyone have suggestions on how to prepare for what I know is going to be a bad time for my anxiety? Does anyone have things they do when they know they are entering into a situation that will trigger their anxiety?

Any feedback would be really appreciated
