Who knows, can't predict.
Remember the woman that survived thousand of feet when her husband tried to kill her by messing with her parachute? Which worked, but fortunately didn't kill her, she had a lot of broken bones though, and was in a body brace for quite some time.
I know of someone that jumped very high, and now they are severely disabled, and in constant pain. Was in a vegetative state for quite a while, but luckily not anymore. A few people survived jumping off that particular bridge, and the doctors didn't think this person would, because they'd never seen it, but did they did.
I used to consider jumping until then. I saw this person in hospital after it happened, and it's put me off for life, because you really don't know what the outcome could be.
You could be worse off, and then you'll never be able to end your life.
Not trying to put you off, I'm merely stating what could happen.
