Sometimes I get extremely violent thoughts about hurting people that I really love & care about. For some reason they all come up & about when I'm around my best friend. I love her, & I'd never hurt her. But sometimes I get the feeling of wanting to hurt her. I know I'd never do it, but the thoughts in my head are uncontrollable. And whenever she sleeps over, and I get tired she says I really scare her because I "turn into a different person"
