Since you have access to a computer, I would recommend downloading a copy of Windows 8 and attempting a repair installation. I can't tell you where to find one, but you should know, you are a college student.
I'm assuming you didn't make recovery media with your computer. You could see if people on your floor/friends have a copy of Windows 8 from the same manufacturer who made your computer (if your computer is a Dell, barrow Dell disks). If you find disks, attempt a repair installation.
Good luck.
