Great writing and very poignant points. However, I feel it to be very important to mention that we do not possess more feelings than that of any other animal, only the ability to catergorise and distinguish them from one another. As well as the capability of being able to communicate those feelings in a coherent and comprehensible manner.
When it comes to suicide, we must consider the energetic processes that are at work in the universe - something science is finally catching up with being able to explain.
If the individual has explored all possibilities and their resulting probabilities, and suicide still comes up at the top of the best courses of action, would it not be selfish to attempt to prevent such proceedings. Thusly, creating a larger imbalance in the equilibrium of the universe.
Though I say this, after enduring my own personal hell for decades, I can give those who contemplate such actions, the notion that maybe, just maybe, there is a reason that they are going through their experience. Sometimes you need a little faith in yourself and the universe, and it will deliver.
Only time will tell, but not if you're dead.
