I'm going to go with suicide depending on the circumstances. I know that my own attempts were pretty selfish and I'd have been leaving a lot of people with unbearable emotional agony. I think in some cases it can be okay, for example: if you're dying of a terminal illness that will first see you physically paralysed and unable to talk. (Fully aware of how hypocritical I sound already!) Since I've posted a link to my recovery blog on here, I'm not going to hide the fact that I'm a constant self-harmer and have been since I was 9. I don't harm so much anymore, although I don't just harm via methods of cutting / burning and would consider behaviour like purging a form of self harm. I guess it's an overly sensitive topic, but I also believe things like DSH are overlooked far too much in society. I'm often made to feel ashamed of my self harm, especially when I've had to go to A&E because I've cut my right arm and can't stitch with my left. The nurses are very patronising and judgemental - it doesn't really bother me too much when I come to remember that they're meant to be treating 'accidents' and 'emergencies', of which I am neither when it comes to self harm.
It's an interesting topic to discuss. I've actually just posted pictures on my blog of my DSH to remind myself that I'll achieve nothing but the promise of a nasty scar by taking a sharp instrument or flame to my self.
Edit: Feel free to ask questions, by the way. I'm willing to talk about it if anyone's interested.
