I took an overdose at school when I was 17. I was out of it, which was my intention, but it got written off as a migraine when I got to tired to go to class and went to the nurses office.

When I saw my rapist at work, I started scratching my arms with the keys I had to hold for opening and closing display cases. I didn't know I was doing it though.

Those are the only two times I can recall.
