Trying to finish Nursing School

I have been through the ringer in this thing called life. During all of the trials and tribulations that I had to deal with I have always stayed in school and kept my head in the books maintaining a 3.5 GPA. I am 1 year away from graduation and completing my degree in Nursing! I am so excited when I think about graduation day but my excitement fades when I think about my current financial situation. I go to school full time during the weekdays and work at least 30 hours on the weekends to cover my monthly tuition but my job has reduced my hours to only 15 or 20 hours if I'm lucky. I can't cover my tuition and other living expenses and fell far behind with the cost of school and I am in jeopardy of being put out of the program unless I can pay the past due amount. Please help!!
