Help simple and effective, yes?

[nxstiskhole]

At night, I plan to sit on the windowsill with my back to the street, stick a knife into the right front part of my neck, in the place under my jaw where the muscle ends on the side and the external carotid artery passes, cut it to the left, and fall backward. Below me are 10 floors and a staircase made of tile and concrete.
I realize how stupid this all sounds, but it will be effective, won't it? Besides, I have no other options except hanging myself from a tree branch in the forest. The money was spent thoughtlessly, and Im renting an apartment with roommates.

Yes, it will be far from painless but if I do all this, are the chances that I will survive or make a serious mistake equal to ~0? Am I missing something?​

apologize for the syntax of my sentences, I skipped English class at school

You most likely won't be able to cut deep enough to puncture the artery and the pain from any cut you do make will have an adrenal response which will awaken your SI more vividly and make the fall harder than if you didn't use the knife.

Im not sure I'd die just from falling, but yeah, when I tore my muscle it pretty hurt
