Welcome to the family!
Like SITC, I'm not in the States so I can't help answer your questions but I do understand how you feel.
Last summer when this all started for me, I got taken into a meeting at work and given a formal warning about my level of absence (I got floored by the flu for two weeks and then got salmonela poisoning shortly afterwards).
I then ended up in the ER one night because I couldn't lift my left leg off the ground without almost collapsing in pain. Had to have a scan done the next day and missed work because of that and my lack of sleep. They had the cheek the next day to ask me "Is that going to be a one off?". Like I regularly plan to spend the night in the emergency room?
Keep smiling and someone in the know should be along soon to answer your questions ~hugs~
