Yeah, I have to agree. Three months? That's still tourist-time! But then, I have moved many times in my life, so to me the move was just an adventure. And, arguably, and escape.
Still, I'd hoped to be able to "fit in" better by getting a job and doing "normal people" stuff, but I'm old enough that I also expected it to be tough to find work (regardless of any laws that might exist, there's still a bias against pimply-faced teens and wrinkly old people). I've had a bit of an existential crisis, on occasion about it - the "I don't belong here" thing. But, then, when I've looked back, I have had that feeling on and off all my life and it's much less here. Or I've gotten jaded enough that it just really doesn't matter.
It was close to time to hang up the spurs anyway, and I knew my chances of getting a professional job here were slim.
But that doesn't help the three-monther's problem. I suspect time would do that, actually. It's a bad place to be in. Wish I could offer something useful that would help. Talking about it might, but it might also make the person who has to listen miserable. One would hope that they could commit for a year, and then revisit the decision to settle where they are. Best of luck dealing with them - it has to be getting old having to have that uncertainty hanging over your head.
