how do i get over the pain that comes with ph?

[c4di]

i dont know if im doing something wrong because i never see anyone talking about this but feeling the pressure of all my weight on my neck is really shitty and i cant get over it so i end up backing out before anything happens. my throat instantly closes and the friction between the front and back of it really hurts, is that supposed to happen? and if it is how do i get over it?

if someone could give me any awnser ASAP I'd really appreciate it, im trying to CTB at this moment
