need to end it

I have been considering suicide for a while and want to know a way to just get it done so that it will be easier on my friends and family. I’ve looked at all the various methods but I Don’t know the quickest way and I’d rather just get it done and over with. I just need it to be over I can’t live with myself I can’t take it and I really don’t want to mess up and live after this attempt because then I would have to face everyone and I just can’t do it so I have to be successful. Please just help me end this.
