Thanks everyone so much for your support.
I have mostly worked things out with my friend. She emailed me and apologized and explained that she was overwhelmed with things happening in her own life. Of course now I feel pretty bad for flipping out, and my husband feels even worse as he was the one who initially got mad at her. But, really, what she was telling us made no sense and we are not telepaths--there was no way for us to know what was happening in her house unless she TOLD us.
I'm very glad I held off on telling my brother anything until I actually understood what was happening. His reaction was bad enough, to knowing how badly things are going for my friend. *sigh* I hope we're all healthy enough to fly soon, my property agent in London is getting annoyed with me, I think. Then again, with the market the way it is, I suppose the seller isn't likely to back out of the deal over a week or two's delay.
I'm still kind of shocked by who put their own problems aside to help me last weekend and who didn't. It did not go at all the way I expected. The next time I have a problem the order of who I ask for help will definitely be different.
