Hi Shell,
I wish I could give you words of wisdom to make everything feel better but I cant. Your Mum is just going to miss you and worries about you. No offence to the Mums out there but you always think you know us kids best. Sometimes you do but sometimes they just have to let us go and discover things on our own.
It does sounds like she will eventually come round to the idea of things. She is just emotional and scared. Its a positve step that she is interested in what you've bought. Perhaps ask her for ideas on how you can make it your own when you move into it. And involve her in that a bit?
The flight is a tiring one as everyone gets older but at the end of the day it's only a day away. Think where you can get to in the states in a days outing then think if you're on a plane where you can get too. It's not that far in the grand scheme of things. Especially with travel getting much easier.
Man Stu and I moved to the furthest place possible from Edinburgh. We cant really get any further away from our folks and mine have already been to visit and have now said they'll visit us yearly or every second year for a few weeks (gawd help us).
Once they realise how close you really are all that scaredness that they have will go away. It does all take time. Just stick with it as you will need your family support as your moving date draws closer. Dont let them push you away.
I know everyone is different and some may disagree but this is what I would do in your situation and just remember we're all here to support you too
