and there wont be too much point in staying here anymore?
Well, kind of depends on what constitutes a "point".
I've been in the UK my whole adult life, and I don't really have any "back" to go to. No old family home or old friends to return to. Whereas in the UK I have my own house, my British DH, friends, and I even feel very attached to this piece of (stupid leave-voting) piece of land that we call our town.
Also, I'm not upto moving countries. I did it twice when I was young, while it was still possible to just pack a bag and go and not have to worry about how things turn out in the other end. It's not the same when you're an adult with family, a mortgage, job, friends and major health issues. The very idea of having to leave my home is just heart breaking.
I have the Settled Status, and I'll be applying for citizenship as soon as I can (really kicking myself I never got this sorted before). I'll be staying here and suffering the shite of depression and whatever else is on its way.
Obviously never say never. If we lose our jobs and can't find new ones in the UK and things turn from bad to worse to horrible, we can always re-assess.
