Why people kill them selfes

This is probably the hardest thing i will ever write in here but i'm not sure. i keep thinking to myself " will anyone care if i just disapear from this world?" who would notice? i hold the blade against my skin and i'm so tempted to cut so deep that i will take my own life. Its not like anyone would care,right? yeah i used ot cut all the time but i promisede my self and my friends i wouldn't dothat any more, but its so hard not to. they all think i'm fine but thats what shows on the outside. take a look on the inside and you will see how much pain i am in. everything around me is fallling down and i can't take it anymore. what makes someone want to kill themselves? i nkow tha tanswer tothis, it's everyone ignoring those people that arein so much pain that they have nothing else to do. all those people ignoring those who need people to do nohting but listen, they all will adventually kill themselves. i nthis i might be talking about me or someone else but myfriends who read this will know who im tlaking about
