I tired to hang myself last year and I tried kneeling position many times when my abusee strikes many times I just wanna die I can't afford SN so someone just tell me how to dive head first. I know a few people who died jumping 5 stories or less
Attempting suicide by heights if the height is insufficient to guarantee death is a bad idea. You will feel stupid when you survive with permanent physical or mental damage, and will just end up more miserable/suicidal than from before you jumped.

Once you experience the mental effects of freefall and the SI kicks in once you jump, you will likely be filled with so much fear & panic that the last thing on your mind, or the last thing you'll be able to control is your body movement. Suicide by heights is physically painless, but the 5-10 seconds on the way down is absolutely terrifying. A fear like that can be counterracted with benzos, or some people can accept that fate for an easier method with no physical pain, but at the end of the day you won't be able to guarantee you'll have control over your thoughts at that point in time.
If you are ever going to attempt this method, do it from a height of at least 40 meters (so 10-13 stories), onto a hard landing where death will be absolutely certain. A fall from 40 meters is essentially a guaranteed death. Otherwise, it's not worth permanently disfiguring yourself/damaging your organs for life. You will just be more miserable than you already are. Do some research on the tallest bridges/cliffs/heights with sudden drops in your area.
