Can you take time ? Draw a breath for a season or two ?
I suspect that it's just been somewhat overwhelming, and time to heal, time to think and be methodical about clearing your feet, rather than feeling hassled and harried to be done on other peoples timetables, would be a good thing.
If things work out as you hoped, then you'll have an easier time selling the house and your move can go ahead with so much less stress.
If they don't, then you'll still have cleared enough space that you reclaim your house and find renewed enthusiasm maybe to find work nearby.
You know now the kind of work you have enjoyed, that has opened up the world for you, given you friendships and a huge sense of accomplishment
Glastonbury lake village is about sixty miles or so from you, is there nothing of interest for you near there ?
I used to work there when it was roundhouse, I've heard it's changed a lot, and the roundhouses are gone, and a saxon house has been built instead. I never got paid for working there, it was all voluntary. Not sure what's going on there nowadays, but one never heard much about it anymore. Nowhere to stay nearby, and doubt they do the living history stuff weekends any more. It was only 2 weekends a month, when I was there.
Tengu, why don't you put the house sale on hold for a year. Do your stuff up in Scotland this summer, then pick up again next autumn, spend the winter clearing the rest at your leasure, and put it back on the market next spring.
The country is unstable atm, I feel it might be wise to just wait and take your time. Another season at the crannog centre will give you more time to get embedded there, and become a more settled member of staff aswell. You can concentrate on that, and worry about the house later.
It's a big life change you are contemplating. It's bound to be stressful, better to take a bit more time over it rather than rush it through and find your health compromised, and then not be able to work. You don't want it to go pear shaped. I admire your tenacity, but perhaps you just need to step back a bit, and slow down, the centre will still be there next year, and you won't have flogged yourself half to death.
Be a tortoise, rather than a hare. You'll get there all the same, and when the time is right.
Sorry, half asleep when I wrote this, dozing off, and suddenly woke up, and realised..... I worked at the peat moors centre, which is totaly different to the lake village, which is not like the crannog centre, its just an area where it was found by Bullied...(.I think that was his name. )
There isn't much there now. No crannog, or round house reconstruction. No work at the lake village. Just sign boards!
