Okay so I lost my USB with all my school work

I have no idea where I could have put it, could have lost it at Avcon, at home or at school. All my assignments were lost as I did most of it last weekend and didn't back it up right away.
Looks like I am going to spend the entire of this weekend catching up and re doing all my lost work D:
So sad, I had a panic attack while tearing my house trying to find it!
