New Laptop...maybe

I found out what happened to my computer today. I was told the lcd display is no longer functioning, the motherboard is fried and the hard drive has crashed. Lol, it sounds like I worked my poor laptop to death. I'm supposed to be getting a macbookPro as a replacement but it and the software that I need come to a total of almost $5k. I've never had that much money in my life so my mother is going to try to apply for a credit card to finance the purchase. I hope the application goes through. If it doesn't I wont have a computer to return to school with.
