I tried not that long ago a couple of times, before I found this site but I had researched my method. Unfortunately my head was so messed up that I thought I'd get away with being left to die if I refused treatment. So although my method would have worked I was treated to save my life. (Ironic though that when I've asked for help because I'm ready to act, but want to be stopped I'm just told I have capacity to make my own decision.)
After my attempt I saw what I did to my family and made a commitment to at least trying to improve things. I agreed to start taking medication again, and restarted therapy. Now I'm reaching the end of my tether again, messing with my meds, finding therapy extremely hard to engage with. But I want my decision to be when I'm sure and not just an act on impulse.
I'm tempted to buy SN, and I have all of the other meds needed just as usual things I'm prescribed. But I'm hesitant whilst knowing I could just act.
