Souls and people „don’t exist“. Because all that you and everyone thinks is you is just your brain taking inputs and making outputs by weighing all its available data. Gut is just another data source which influences your brains actions.

prevention is better than cure, because if you have to cure it you already have the disease. the future isn’t set in stone (theoretically).

Sadly also not a good idea. If you don’t get killed (which is quite likely) you’ll have pretty much the same issues as before. Doesn’t kill you, can very much cripple you, but this time you will get a life sentence, maybe even with suicide watch.

If you can’t bring yourself to do it, be it because you think people will suffer and be sad when you’re gone or that the world will be a worse one without you then you really shouldn’t do it. You most likely don’t actually want to in that case. There are exceptions, like terminally ill people who just can’t anymore, but if you have doubts about suicide, then you should see someone about it. Also, you will very likely survive ~35 meters. General rule of thumb is 50 meters for hard surfaces (concrete, compacted dirt, rocks) and 100 m for water. Please don’t jump from there. You will cripple yourself and hate yourself for that attempt forever. (There’s most likely a safety net too, so you’ll break a bunch of bones if you’re unlucky)

Don’t. KCN is incredibly painful. There are better ways.
