Overwhelming student debt and sick parents

I am a single bright girl, grade A student all my life and have worked really hard but now seems like hope is far from near. I went to Business School for my Masters and then explored business ventures. Things did not go as planned in business and as a result I garnered huge amounts of debt. While I was just trying to get out of debt, my mother fell really sick and her medical bills started to rack up. I have to now look after my mother's medical bills which is a priority and also get out of debt I am deep down in.
