I know that I don't know you, but if I did, I promise that I'd jump off a bridge for you to stay alive. Nobody really has a purpose but many people would miss you, I know that although you're just an internet person, I would be emotionally scarred if you left the world. I'm sure your family and friends would care too. I really don't know what else to say... IF YOU GO DOWN, SO WILL I. Please don't ring the police, but I will. It' not just an empty threat, this is serious.
I know how you feel- I tried to kill myself only last month but my 12 y/o brother walked in and I couldn't let him see me do it.
Just...please don't.
I really shouldn't give advice though, I sound like a hypocrite seeing as I'm always having suicidal thoughts.
Sorry if this doesn't convince you ;.;
