I grew up in a family that's been peripatetic for generations. Of my eight great-grandparents, at least two grew up as expats: Scottish people in Germany, French people in Italy. Four of them moved continents (before meeting each other!); of the rest, only one of them stayed within a few hundred miles of where they grew up. I can tell you stories about all of them.
I live three thousand miles away from my parents. My husband moved in his thirties from the UK to Australia, and then in his fifties to the US. His adult kids are in Aus.
We all manage to maintain close, lively relationships. We talk all the time and prioritize visits. We don't go for conventional holidays: travel is either work trips, family visits, or ideally both. Two weeks ago, a cluster of us were all together in Montreal. Next Christmas will probably be in Australia and the following year in the UK. Right now, my dad is here in California, sitting in front of the fire across from me as I type this.
It's not for everyone but for us it's been good. We feel at ease in the world, make friends easily, and we're solidly involved in each other's lives.
That said, I understand your distress, OP. I mention this simply as an example of how families can remain close over distances. I hope you can find some peace with your daughter's move.
