Help Fsh passing out help

[sickofeverything]

I got a thicker rope which seems to be better due to less pain but I am still struggling to pass out. In the videos I watched most passed out right away but some struggled and seemed to have a painful end due to not passing out. I tried putting my weight on the rope and it tightens and the knots are good, it makes it hard to breathe and I start chocking a bit but no tingly/pass out feeling. I worry when I go for it and do fsh I won't pass out. My knot is in the back and pre tightened, the rope is at the top of my neck and I tried pushing down but nothing. I know it may be different when I go full but even people who do partial seem to pass out in the videos so idk what I'm doing wrong or how to fix it
