I didn't think anything during my last moments when I attempted a few years back. On the way out to the door I was anxious and I felt sad saying goodbye to my dog, but soon I became numb and hell bent on death. I think taking an insane amount of benzos contributed to this.
Recently however, I didn't attempt but was purposefully destructive and had a moment in which I truly thought I was going to die. I drank a ton of alcohol and slit my wrist, and ended up bleeding for hours. Not just a little blood, but steadily pumping hours later type of bleeding. I eventually went to sleep on my floor with my arm wrapped up, and later woke up to puke. I then passed out, smashing my face into the tile floor. When I awoke my body was jerking uncontrollably and I hurt all over as I violently moved. Once the jerking stopped and I gained control of my body, I could barely breathe. It was then I thought I was going to die, and I panicked. I had fleeting thoughts of my dog, and how there was blood everywhere. I was very scared and I scrambled for phone to get help as I didn't want to die. I just wanted my dog. Couldn't find my phone though, and I ended up pulling through. I was so happy when I went into my bedroom and saw my dog curled up on the bed.
