Usb stick is not working?

Well today my usb stick completely stopped functioning. It’s not physicallly damaged and it still has its red light flashing but none of the computers recognize it when I put it in. There is no error message and it doesn’t seem to connect to any of the computers at all.

Is there a way I can recover data from it (Yes, yes I know usb’s are a bad storage device but I wrote a massive part of an essay on a public computer today and when I came home it refuses to work) or do I need to visit a specialist?
