I dont live on an Island, but I can spit on the Mull :)
I moved from London to the NE of Northern Ireland , very remote, rural, small community
I remember my first weeks here, seemed every where I went I met English people , all heading back to England as they had had enough of the winters here . Indeed the day we came off the ferry , the snow followed us up the road and by time we got the keys to our home, the snow was a foot deep and it was with us until the end of April
Since then we have had some really dire winters.
We have short days, daylight is 8.30ish am to 3.30ish in the winter, but then come July , we dont get dark.
And Ive slowly acclimatised. Where as in London Id still be wearing a jacket at least at 16oC, now its get the shorts on. It was 18oC here this afternoon, shorts, vest, sunhat and BBQ and sat in the garden amongst the midges till 9pm
Moving to a small community has its own challenges. It really is all about what you can bring to it. You have to give to take out . I ( being English ) was so very lucky that the local pub needed a hand out one weekend, I offered - having always worked in pubs part time over the years - and from that weekend, got offered hours ad hoc. It meant that I got to know people very quickly. I did get some stick from some, but I had to suck it up , show that I was a person, not a nation and get on with it . Getting to know people, meant I was included, job offers came, help when needed was offered
When you live remotely you have to be hardy and have to be adaptable . We have had long power outages - weeks - not hours - for instance, We share our resources with not just immediate neighbours but further afield if we can. We know everyone in the locality and look out for each other - without living in their pockets. That means also everyone knows your business , which is a godsend at times, bloody irritating at others
Our nearest inhabited Island is six miles off shore. Has a population of 140. The kids at secondary and above have to board over here to attend school. Last I heard the primary school had 3 pupils. There is no doctor or dentist, community nurses do week and week about. Emergencies are air lifted No petrol cars allowed as everything - including fuel - has to be ferried over. Storms stop the ferries We have a lot of storms , even gale force winds that arent even given storm status will stop the ferries.
Living remotely is expensive, everything costs more, especially fuel - be it heating, lighting cooking or travel
