Why are you having to support your family members that can't work? That's still a choice you're choosing to make (and, provided they're American citizens and are older, there's a chance you're screwing them out of Medicaid help in 5 years...). If you start taking on too much of the cost of your family's care, you could end up doing it for the rest of their life.
There are other social support systems (which people on this board may or may not agree with, but I digress) that won't make you lose your sanity, your grades, and your health.
You can still do things to support your family that doesn't require taking out more than your school's COA. I try to help my mom and stepfather, who don't have a lot of money, out. But, fortunately, my mom's on Medicaid and Medicare due to numerous health problems. I buy them things they need occasionally, I pay to fly across the country and visit them, and I'd help them out in an emergency, but I'm certainly not going to work 40 hours a week while I'm a student to pay off my mom's hospital bills from when she was uninsured.
It was 90% personal 10% school, but the personal crap made it really hard to focus on school.
