Looks like you could have lost all your work I am affraid, its really important to back up important documents but not on an memory stick - best thing is an external hard drive. Personally with Uni work I email myself it regularly - that way I have a recent copy whereever I may decide to work on it from.
You may be able to salvage it - it just depends on where it has snapped, if it is the board then I would say you'll never see your documents and photos again, but if it is the usb connector you may be in luck.
Its not easy to diagnose this issue over the www, so if you can give more information then we might get somewhere. Can you tell me where it has snapped - or send photo of it? I can give you my 'junk' email address on here. Let me know if this is an option.
