MacBook Pro flashing folder with question mark - NO installation/setup disks

I recently bought my Macbook Pro in August of 2012 and I have noticed that the newer MacBooks do NOT come with additonal installation disks or anything of the sort. I started up my Mac today and was faced with the flashing folder with a question mark on it. I already know what this is implying and I have tried literally everything to fix it. It does not recognize command-R so I cannot choose HD recovery and when I try to perform "first aid" on it, it does not recognize my disk-0 and when I try to verify or repair, it does not let me. All options are greyed out. I have tried resetting the PRAM but that does not do anything either and I cannot boot it to single user mode. Please help. The last thing I want to do is bring it in for repairs as it is my last week of classes in university and I absolutely need my laptop for school work.
