I understand and feel the struggle. Overwhelming is the perfect word, no one understands, other than those going through it. I too lean on my husband for support, he tells me dont worry, everything will work out and be ok. But he takes it personally too, like he isnt doing enough, when after all what more can he do but sit and wait.
It is hard thats for sure, in my situation, my license has lapsed and until Ill get the temp perm res card, I cant drive. On top of all that, my father passed away 2 months ago and I couldnt go back, luckily my mother has my brothers and my oldest daughter there for support. Family has visited, but its just not the same as going home and seeing everyone at once. Looking forward to when I can cuddle my grand-babies in person, instead of seeing them via pictures, calls and Skype.
If you ever need to just get things out, mail me, Im a good listener, maybe we could commiserate together

Best of luck to you in this journey of wait and see.
