I reached out on HN mostly because I'm hoping to find some other crazy old men, as I've known quite a few people in my direct career field who I could be describing in this way (washed up young, formerly successful, diagnosed bi-polar or schizophrenic (I'm thankful I'm not schizophrenic. I've been to a few funerals for them. Most people my age from the bay would remember a sysadmin named SLF when I say this). )
My kid I don't interact with much, I decided a long time ago it was better to keep them shielded from my craziness. Now it's just text messages & international adventures once a year.
