It's a really strange mixture of emotions, that's for sure. KFDancer is right, of course, but it's a bit easier said than done -- I really hate the feeling in limbo, which makes feeling really 'present' here sort of impossible. It's silly, because I know I'll miss plenty, but it seems I can't enjoy anything while I'm waiting for this application...
Well, it would be one thing to say, "Enjoy your last 3 weeks in the US." I could. It's a completely different situation to say, "Enjoy your last weeks/months in the US because you can't plan anything permanent, can't leave the country, and can't spend any money because you don't know if the visa will be rejected and you might have to spend thousands of dollars to re-apply. Oh, and try not to worry because you can't get medical insurance for your very uncertain remaining time, and you've already run up hundreds of dollars in medical expenses due to two separate medical incidents. Other than that, have fun!"
So, it's not an easy proposition. Plus, I don't have anyone to help me here, so I have to worry about closing my apartment, selling my car, turning off utilities, closing bank accounts, etc. etc. right at the very last minute on almost no notice. Would be easier if I could stay with friends and family and pick up at a moment's notice.
But still, I am trying to enjoy my last few moments here.
