To do list item (advice to the brother I don't have):
Get your Hepatitis C treated now. Whatever medication is the right one for you (and people need different Hep C meds depending on various things), you have to do your best to take that medication perfectly. One day at a time... but every day.
12 weeks of most first-line Hepatitis C medication costs more than an SUV, and you gotta ask yourself: is the new Congress going to keep appropriating funds to buy you an SUV? Even if that SUV would save your life?
