First, I can't imagine what you are going through. I am very lucky that our family is all together under one roof. I just wanted to write and let you know that it would be perfectly normal to feel so down about all that is on your "plate" at the moment. Heck, I get down and my kids are in the next room and I'm a stay at home mom!!!
I'd be a total mess if I had to handle what you are going through. You are obviously a very strong woman, even if you don't feel like your are at this moment!!!
I wish you the best!!
