My FlashDrive is not being recognized by any computer...

Hi,
On 11/13/15 I had plugged my flash drive in the school computer and it was working fine. But after a few moments later the entire computer crashed, and broke my usb. I have plugged it in about 20 different computers, almost all different versions, and it still will not be read. I have tried TestDisk, Disk Managment on the computer, but I have not (and will not) try to restore the flash drive. I have some very important information on this flash drive and can not risk to restore it. Please help....
I got this flashdrive from 5below, and have had it for a good 2 or 3 months and i have never had this problem. I have always safely ejected it from the computer. And i dont understand why its not working...

Thank You,
Fait
