Partial hanging was pretty peaceful for me when I was severely depressed. Fearless and wanting to "see" what non-existence is like, I tied a clove hitch knot to my anchor point, a hanger pole in the closet, and a slip knot on the other end to hang on. Tightened the rope at the middle part of the neck at an angle to put pressure on the sternomastoid muscle to compress carotid arteries. I then kneeled, and went numb then started to lose consciousness in 15-20 seconds with zero pain. I've done it hundreds of times for 2 years and felt calm and comforted every time I did it. Comparing it to now, being unconscious is better than sleeping with strange dreams and nightmares, but dead is infinitely better than just unconscious.
I was almost free and still suffering because of my indecisiveness.
I hope your death is free of discomfort.
