Ditto what Margo said. What you need is distraction. Do something to change your state of mind, and what's best is usually something physical. Can you take a walk or get you and dh in the car and go out somewhere that you won't have to interact with a lot of people? (Or maybe where you DO.)

Maybe there's a nice calm place you can walk around with your husband--a botanic garden or something? That way you can still sort your thoughts, but have more opportunity to focus on something else? Even if you don't feel like it, give it a try, knowing ahead of time that you can leave if you really can't handle it.

I often use this idea with my children, kind of a 3-way communication. They tell me more about their thoughts and feelings when we're doing something else that doesn't require too much attention, like a hike down a nature trail. I suppose there's something mind clearing about it.

How about some stream-of-consciousness journaling? Pour it all out on the page.

Do something else to make the time pass, because that's the goal--allowing the time to pass. Don't think too much about when your husband will be away--it's still a ways off and this can all be over by then.

Still vibing,
