Panic – Live Mail – deleted my inbox and sent box by mistake and had very important family records in it that are lost if I cannot recover email. Oh please can anyone help.

I just signed up for Windows Live mail a short few days ago and imported all of my email from my other email account (phone company internet mail system). I had it set up to import email from my other email account and it deleted both of them. I am in a panic because I deleted them yesterday or today and have nothing left in either my original email account or the Live Mail account. I thought they operated separately. Help, help, help! Sobbing hysterically! Any help?
