> I'm a pity case and an example case of how not to throw one's life away.

You may not be envied, but there's nothing wrong with not having a wife and kids. I'm a bit older, had a relationship/marriage for 23 years, with a child, but we divorced. Online dating was depressing for me, so I live alone now (although I do frequently see my daughter), and I'm in peace with that. Currently worried about my elderly mother, though.

You haven't "thrown away your life", that's American movie bullshit. Get a job, feed and clothe yourself and enjoy the simple things in life.
