I feel pretty bad

I feel like a bad person

I know that its kind of dumb, but I feel kind of bad for being mean to the kid that SA me like 8 years ago. Neither of us knew better but I still treated her like shit for it and I feel really really bad. We still go to school together, and a few months ago I went to the nurses office to take my medicine and because I had a headache. I wanted to go lie down (there are usually like bed things in the room) but I turned to the part of the room where I could lay down and I saw her, and I just said nevermind and left. Ik thats not technically treating her like shit but It most likely made her feel like shit. I used to give her dirty looks every single time I saw her, and sometimes still do, and one time I even made her cry. I feel so so bad and I just want to apologize because although I haven't gotten over it, im not mad at her for it, she seriously didnt know better. I feel really bad. I used to be genuinely scared that she'd kill herself if she felt bad enough. Idk why I was so rude.
