By which I mean the kind of thing they make tv programmes about - leaving commuter life in London to live on a croft in Scotland, etc? Or selling the house and opening a campsite in Italy? That sort of thing?
I am exhausted, irritable and fed-up all the time, despite having a 'good job', 'nice life' etc. I live in the south east and the thought of another 20 years commuting into London to do the job I have lost all passion for, just so I can pay the mortgage on a semi in the suburbs, is really starting to get me down.
I'm not materialistic and often think I could manage with far less than we currently have. DH is the same, pretty much. He's always said he'd happily live in a static caravan and, while I wouldn't go that far 
I am not bothered about 'keeping up with the Joneses'.
The dc will be off to uni in a couple of years and I'm wondering whether we need a big change.
I'd like to move to a Scottish island and buy a b&b (I know, I know!) DH and I both have jobs (teaching, HCP) we could fall back on reasonably easily if it all went tits-up. Or is this just a midlife crisis talking?
