It's a sad fact but it's the same here too... sometimes you have to stand in the middle of the busiest corridor and just scream and cry until someone comes. And don't stop until someone who can give you some answers gets there. I can't believe they're too busy to talk to you!
Sending heaps of love and hugs from here, it's the "not knowing" that makes it so hard. If you have a plan you have something to focus on, but when they have no idea what's wrong, it's so much worse.
