The worst is yet to come for me.
Either someone I truly love (wife/children) will die/get very ill.
Or I will die without having truly raised my children to an age where they're old enough to develop strong without me, creating a host of emotional abandonment issues that will plague them for the rest of their life.
Neither are in my control, but it's all inevitable. I find it difficult to embrace this inevitability. My only solace is that every single human being on earth will face the same conflict I will. Life will go on and no one, eventually, will care that I ever lived, so whatever I'm stressing about isn't that big of a deal...even what I mentioned above. Since one day, no one will even care that my children, or their children, ever lived.
