I feel similar but I wouldn’t say I particularly hate my parents.
I was an accident and honestly if anything I’m very frustrated that the only reason I was born was that my grandmother is super religious and refused to even entertain the idea of an abortion, hell she’s even responsible for my name (again from the fucking goddamn Bible. For me that’s ironic since I loath most organized religion.) but my parents in no way should have gotten together. I think my mom was just attractive and my dad is a pig for sex (I recognize some of that in myself so I guess I got that from him… Thanks…)
As others have mentioned it’s not so much that the entirety of all 38 years of my life sucked, but for me I have a distinct memory at 11 years old of having this feeling that something wanted me to kill myself because it just kept “poking” at me, making life miserable in various ways. I gave the sky the finger and said “fuck you I’m not doing that” simply out of spite of whatever it was. (I don’t believe anything like that now). So I have to imagine childhood wasn’t as bad although I did have to live through 2 stepfathers that both wished I didn’t exist probably as much as I do.
Anxiety runs rampant through my father’s side of the family and I’ve definitely been depressed for the entirety of my teenage and adult life. The world wouldn’t be affected by my passing, but I sure as hell would love to hit the “off button” as well. All that said, if women even found me worthy, I would never want to pass these absolute garbage genes on to anyone. That should be a crime thats how shitty they are (except my immune system, that seems pretty ok lol)
