I've tried the second method.
First time i used a way to thin rope, connected to the door handle, threw to the other side of the door and hung myself. As i said, the rope was to thin so it broke. Passed out really really quick to the point i woke up on the ground shaking not remembering why i was on the ground.
Second "try"(not even a real attempt) I bought a thick rope that should handle my FULL body weight.. I tied it to a wooden beam above my stairs. Tried to pass out but I couldn't! Tried it a couple of times over a couple of days, but just couldn't pass out.
Finally found some info here on SS (which atm i thought was stupid) that helped me pass out: don't put the part of rope from your neck up to the beam right behind you, but more to the left/right.
It took sometime longer than my first try, but at least i got to pass out.
Problem here is i can't like lean backwards, so i just bended my knees untill i pass out. After i pass out, I somehow stand up regaining consciousness.
I was thinking of any of the other methods from the picture, like the third method, with my legs more or less down the stairs so it would be harder for me to get up while passed out. (but would it be harder tho?)
The fourth method seems like the second method only way lower. I figure if i somehow get up with method 2, i will at method 4 to.
The full (first) one is something i would not want, but when no other options so be it.
tl;dr: need help NOT standing up while unconscious
