Method + Family.
If I had a weapon I would probably have done it spontaneously. Having to order SN or N, chances of impurity, messing it up and surviving with brain damage or legal problems kind of puts me off it. For now.
Family of course is another reason. I am in mid twenties and live alone but got young siblings, ideally wouldn't want to leave them, or my parents and grandparents. I kind of annoying because of this though - I don't want to be held down by thinking about how they will, as I already feel terrible and tried loads of things to help myself. So last thing I want is thinking about how they will feel, when I feel so shit.
