I don't remember exactly where I got the idea, but I think it was on a teen website I'd been on a few times that was created to help people struggling with depression and other mental health problems. Their self harm forum wasn't the greatest and instead of discouraging people to SH it kind of gave you the idea instead. Plus I had talked to my friend about it a couple times because she'd thought about doing it before. It was during a time before I found out I was depressed and I think I did it because I was confused about the way I was feeling more than anything.
