Help Complete Doctorate Degree Journey

I am not the type of person to ask for help. All who know me, I will give my last dollar to you if you need it. I have come into a pickle and need your help. I have been paying out of pocket for my classes to finish my Doctorate Degree. Last year I was told I cannot receive any more student loans to finish school. I have applied for other student loans and have been denied because of my credit from my student loans. This semester I need to take 2 classes, I can afford to pay for one class a semester but have to take these 2 so I can stay on schedule and graduate on time, my books are 500 and I have to go to Lynchburg for a week, the cost is 675 for room for a week. This is all included in the 3500 I am asking for any help I can get to complete this task. I am humbly coming to you all as this is very hard for me, but I have no where else to turn.
