Heart Attack

Oh no! I just accidentally clicked on the 'empty' tab of my yahoo mail account. Does anyone know how to retrieve the emails? I am about to have a heart attack because all my work and school files were there, not to mention some personal emails which I would have loved keeping. This is what I get for multi-tasking and when I say multi-tasking, I was texting, chatting with a friend and reading my mails all at one time. I am officially blaming you Jefferson for this!
