I've recently had a failed attempt, so I have figured it out.
Immediate family. No real friends. Wife. Nobody in the wider community.
My two small sons are the ones keeping me here, and the ones who would miss me most. They are 4 and 6, gorgeous children. Pity that Dad is a basketcase.
I draw scenarios in my head about their happy ending. My wife mourns, then meets another guy. He's awesome. Nice house, car, boat. Coaches the sports team. Soon enough they call him dad. When people ask my sons about their real dad, they will be like "oh, my real dad died when I was 4, its OK, (new dad) is my dad, he's all I've ever known"
