Thank you guys for sharing your experiences. It helps just to know I'm not completely alone with this. Sometimes I look at or hear about families who work out just fine with distances and wonder if I'm the only one.
Sha - Thanks! I'm excited. Well, mostly. Some amount freaked out, too.

Also, I can completely relate. Dad was diagnosed with cancer not long ago and 7 weeks later, we lost him. I am thankful beyond words that I was relatively close and could afford to hop back and forth almost on a weekly basis. Considering how little we had left with him, I wouldn't have missed one second of it. I can't imagine the dilemma that being so far away causes when something like this is going on.
Omoba - I hear you on the grandkids - great grandkids front. We don't have any little ones yet but I already feel bad about their grandma not being able to see them more than twice a year.
As far as talks with the hubby - I can usually talk to him about most things but somehow, he can't seem to relate to this guilt-issue. It was mentioned earlier on this thread that this may be somewhat of a foreign issue to Americans as they are so mobile. To make matters worse, a good portion of my friends (at home) also, well, not disapprove of me but they don't understand how I can be so far away from family and home or why I would even want to.
And Nini, I know what you mean about the 'are you sure about this?' discussions. My brother has a particular dislike for America and Americans in general (neither of which, I might mention, he knows to any degree) and quite clearly is of the opinion that I very possibly lost my mind. I think just overall, he and Mom can't associate with this wanderlust of mine. They don't understand why I can't just go home and sit still. I'm a bit of a black sheep. Dad, I think, had no problems with it.
Anyway, guys, once again, thanks for sharing. There is comfort in knowing the problem's not mine alone.
