Suicide can be very difficult as even know we want to die, we are programmed to survive. More than anything I wish that it was easier to leave all the pain behind and be free from everything. I think that many people get the courage to leave when they reach the point of desperation and the pain of living gets to be unbearable, all they want is to escape this world and they are determined.
However, of course I do not really know as I am still here after all. I do believe that if I had a guaranteed, peaceful way to exit this world, then that is what would give me the courage to leave. The fear of failure is what holds me back. We all deserve the option of a death which is like falling asleep and never waking up.
