Any help? Don't wanna get expelled :/?

[Chris]

This girl started texting me on facebook asking dirty stuff and being a loser 15 year old guy I went along with it. Stupid I know. Then I found out the account is fake and it is someone at my school (I don't know exactly who) who may use this to try to get me expelled. I never said anything bad really,when "she" said something dirty i would just say "yeah lol" or "ok lol". Is there anyway I can trace the account back to who is doing this? I really don't wanna get expelled. Thanks to anyone who can help.

i think its impossible to trace, my only advice to you is delete your original facebook account, so there will be no traces that will point you on having dirty conversations with that bogus (unknown) person.
