Recover Photos

Hey guys,

I need help.... I've had my Hotmail since I was like 9 years old. I've stored pictures through all my teen yrs, from my travels...like.. my whole life. 

Last time I logged in to my OneDrive was probably May, just to discover today everything is gone, completely gone. Please tell me there's a way of getting it back? I've tried to go to previous versions and I can't even see where that is.
