Antlers, I'm so sorry you got the secondary bomb last night - for me it was this past Sunday, and I'm still reeling. I don't have any advice that hasn't already been given, but wanted you to know you are not alone, I am in the same boat in the same polluted swamp that you are, and we will make it through this.
I had the additional insult to injury of having my dog die yesterday - that's 2 in the past 4 months and 3 in the past 2 years. Like you, I really feel like my family is disintegrating around me, I can do nothing to stop it, and it hurts worse than anything I have ever experienced.
Someone posted "Next time, just stick a fork in my ear, it will hurt less", and it struck me as funny - like Homer Simpson says "It's funny because it's true"
There is some good advice on my thread, so you may want to jump over there and read it.
