Should i make a facebook?

so i had to leave my old school because i was a horrible person and i did a bunch of crap that made all my friends turn on me and become vicious and mean to me so i went to a new school and made a new group of friends and there always asking why dont i have a fb and telling me to get one but i know if the kids from my old school added me they would probably tell my new friends all the stupid crap i did and they would be really me so id have to deny their friend request or whatever and then my new friends will be my only friends on facebook and then theyll see that and think im weird and have no social life etc.. so idk what to do cause i feel like i cant be the only one without a facebook forever..
