Dont be panic dude.I am sorry to hear that but one of my friend had had more harsh situation than your. He had lost everythig ( Actually his apt was robbed).passport,I-20, original certificates up to bachelor level , everything.but he went NEPAL and got every thing again without any trouble. So, u need not to be worried so much. if u want to talk to him email me along with your cell no I will make you touch with him, u can get some idea,
