Its Lost!!!

I lost all my bookmarks!!! All the blogs i read were there...All my favorites places, crochet, knitting, patterns..All gone, never to be found....It was all deleted by mistake.....*Sniff*.....
I even did a system restore and nothing....I thought for sure they would all be back, but no...
If any computer brain is reading this and knows how i can get them back, please let me know...:-)
