Hello Dawn
Sounds like a hard situation for you, with mum so far away.
No, you can't expect your family to move to Scotland, that would have to be a major decision that everyone agreed to. Is it possible to investigate care in England, close to you, for your mum instead?
I'm aware that funding arrangements are different in Scotland, so you'd need to look into this.
Would your employer let you alter your hours so that you do get two days off together, or could you take holiday on one of the days, so as to get to Scotland?
On the other hand, if you've rarely visited your mum, perhaps you don't need to visit any more often now, even though I'm sure you want to. She will be used to you not being there, so that might not be a problem to her.
All are possibles. Have a think on my suggestions, and let us know how you go on.
Love
Margaret
