I was a complete idiot last year and I’m going to face the repercussions now.

I was a idiot last year and I was only a freshman and I thought I would be funny if I cursed and was homophobic and was just a jerk overall. I grew so much as a person in that year and a half, and now someone is going around showing the principal screenshots of all the freshman from last year being idiots, and I am afraid of getting in trouble. What do I do?

P.S I understand that I’m in the wrong, but I’m just scared to get in trouble :(
