Oh gosh~ I am so sorry that life has been so hard for you lately. I can totally relate to needing a quiet place to get away from everything for a while. Your dog sounds great and I admire you for wanting her to have a home and not be euthanized. Have you tried contacting a rescue group for her? Have you placed an ad in the paper? BTW, she guards toys because she is a herding dog! You should have seen my australian shepard with my kids when they were young! Oh brother!!
It's hard when your family lets you down; negotiate with them for a repayment schedule maybe. The economy is tight and money holds a lot of power.
Work? Yuck. Where do you work? Can you change jobs and find one where you will receive a little more respect for being a human being??
Your day sounds like it was really crummy and I'm wondering if today was any better for you...........
