*please no advice on staying alive, I've already made up my mind that i want to die in the next year or two. I don't want to see 25 years on this planet
You cannot legally sell your organs in the US. You can register with your state as an organ donor and you can donate your body after organs have been removed to a local hospital.
In the US totally illegal to buy or sell organs
You can donate them but you can not sell them
I know you don't want to hear this, but I'm still going to say it.
Please don't do such a thing. Things may be hard now, but they'll get better soon. You have a long life awaiting you.
I promise you that it'll get better.
Your suicide will probably render your organs unsuitable.
Don't think you can do this pro-actively.
Do you have borderline personality disorder?
