It is a problem of the modern world.
The cities suck in those hungry for success and wealth and spit them back out again into more sedate parts of the country.
I fully understand what you are going through, in one half decade Edinburgh grew 20% in population with EU immigration, but services remained flat and funding even flatter. No way of getting doctor or dentists appointments.
It took 2 decades for services and especially budgets, to catch up.
I must admit I find it hard to put myself in the position of someone who grew up in the family village. I am a child of two forces parents who met and settled in a part of the country neither was from. More than 400 miles separate. The centres of my two families and I left to join the Army at 18 then never went "home", if that is what you call it.
I cannot imagine simply suffering where I live simply because I never lived somewhere else.
I know it is not very sympathetic, but, then, my world is not constrained by artificial borders set by where I was born.
