In case you haven't done it yet, lol
I suggest cutting your throat, you may gurgle for a bit, but its a fast way to end it.
another way is overdosing, honestly just take a lot of pills until its all over, it will take a while unless you know what pills will do the trick, maybe other people will have ideas??? I don't know much since every time I try to commit, somebody sees me and I get sent to a mental hospital.I hope these are useful. :P
