Cant say what it's like as someone living it, but no , you don't die soon after. An ex of mine attempted death by hanging (I'm quite sure it was full suspension) and would have succeeded had he not been found. He was found within the period of time that he was able to be saved, but will never speak , walk , be independent again, etc. It had been too long without Oxygen getting to the brain. He was unconscious for a bit, but honestly as stupid as it sounds, we thought he would recover, if not fully then mostly. We didn't realize how difficult it would be from that moment on, and I'm not sure that a lot of people do. Even though he is still with us, sometimes I feel it's more painful to see him that way. But then sometimes you think you see a slight reaction that fits perfectly with what we recognize as understanding and responding and then it sparks a little something inside you. We can't really say he is suffering, or that he even understands fully that he didn't succeed, and that's one of the roughest parts of it. Just know that no matter what method, this is never something that you can guarantee will not happen to you. He is damn near unrecognizable, sadly a shell of the man who served his country proudly, the father of two beautiful and smart children, and the wonderful human being he once was, no matter his faults or mistakes. I hold onto the fact that these pieces are still alive and well inside him, and that he has such a selfless family that is so overwhelmingly happy to still have him in their lives that they've sacrificed so much to give him the best quality of life possible.
