REQUEST: Tuition Assistance

I'm getting a doctorate and the school (built by slaves, named after Christopher Columbus) charges me fees every semester to continue to study there. I can't afford them and I'm not sure what to do. I already work an outside job and can't ask for money from my family because they are poor too. I will go crazy if I have to get one more job while working on my dissertation. I am also maxed out on student loans. If anybody can help, please do.
