Those of you who say that the lack of sex and love is not a valid reason for ending one's life, are you aware that "skin hunger" is a drive that makes humans need touch - be it sexual or non-sexual - and also that being lonely is as dangerous as smoking a pack of cigarettes a day?
As a male, I can say that it's hard to live without a significant other to fall asleep with and just to be in the company of.
Dismissing the need for sex and love as a valid reason to end one's life is like dismissing the wish to end one's life for reasons such as chronic pain or financial problems, or any other reason. In the end, we all have our own reasons to want to live or die. Being without sex and love feels like the world doesn't care about you.
