I am being haunted be e-mails

Tonight, I logged into my GU account for the first time since taking a year off. I thought they did a server dump at the end of every term so I would be logging into an empty account. Nope. There there were. All of my old e-mails and copies of past papers mailed to fellow classmates for critic and feedback. I almost had a panic attack just seeing everything there. I thought I had come to terms with it all but I guess not. Right now I am wondering: Am I going back too soon or is this just confirmation that I made the right choice by switching?
