listen to me, in the time I've known you I've come to love everything about you. From your smile to your personality, from your attitude(that's a reference to your fighting spirit cause your still alive  BTW) to your caringness. There's not a single thing I or someone else don't like about you. I bet someone is willing to spend all their money for you and you know what they wouldn't care because in their mind that's money well spent. Someone is willing to do anything and everything for you. **** they'd **** myself if it meant letting you live.
I've been through a lot in my life. I've lost quite a few friends to suicide and the one thing I've learned is that all they wanted was help. You have people who want to help. You have people who love and care about you, I'm one. Not only do we care we care deeply for and about you. I'm not giving you an ultimatum because I could never do that to someone I love. I just want you to think about how much it would hurt me and your friend and all the other people you've met and inspired. You did that? Now think how it would feel to you if your killed himself or herself. That doesn't feel to good, I know it doesn't because that's how I've feel many times.  I may not know you as well as your best friend but I know you care about other people. This time though you need to care for yourself. Take a moment and just think about me and your friend and if it helps a third friend as well.
You've done that? I bet you feel happy right? Now think of all the good times you've had with then. Lastly I want you to think of your life goal. How would you achieved that if your dead?
