Help Help with partial hanging

[spongebob4]

I might maybe hang myself with a bath robe tie because I can't get rope. And the part that I will hang off of is the pole in my dorm room closet, it's about chin height up. Should I use a slip knot or a noose or another type of knot? How should I kneel down and where should I put the pressure on my neck? How long will it take to pass out then die? What would happen to me if it doesn't work? How do I get over SI and thr fear of the void or hell after dying? Is it ok to practice and not do it? How risky of dying or harming myself would that be?
