Blair,
Not alot to offer here except for thoughts and prayers. You are more than welcome to come stay with me, but I'm in Southern Indiana. I live on a big farm, though, so it'd be nice for the dogs! hahaha!
Just stay focused and be proactive. Do all of the things that jjfritche said. Call ahead to EVERY place. Even if you feel like its overkill. You'll need to have back-up plans, even if it seems like something is going to work out. Remember, REAL WOMEN HAVE BIG DOGS. So, that makes you a real woman, right? Do what you gotta do for your kids and your furbabies and just make it happen. We're all rootin' for ya, we know you can do it! There's nothing to fear but fear itself! Umm....see it, be it!!! No matter if you think you can, or think you can't, you're probably right. (Eleanor Roosevelt)
Do you have a tent? Just pack it and a bunch of food and water up, and pitch that puppy somewhere dry! Just load it all up, and head out! You don't have to know where you're going...well, actually, you DO know where you're going, Blair...TO SAFTEY. That's all! You have all the tools you need to be safe and secure. And there is alot of love and support out there for you.
Good luck, girl! Take this bull by the horns and shake her around a bit!
