Thank you all - the venting really does help. Most days I can keep it all in perspective, but some days are harder than others.

We're making changes in our lives that mean we will be OK financially. We're planning to sell our house in the spring (and believe we will be able to), which is a good thing - we're in a different place than we were when we bought it. We have contingency plans on top of contingency plans. But - when things are tight - having those who should be offering support (emotional if not financial) taking advantage of you just gets tough. Particularly when those people refuse to consider making hard decisions that they should be making. I'm an only child with divorced parents, and my parents are crashing and burning at the same time.
