ADHD-PI at 38.
Well, it didn't help except to try psychiatric meds that I can't tolerate. 25 years after dad declared "Damn psychologist [sic] quacks don't know what they're talking about. They're liberals trying to control boys with medication. It's a myth!"
And now I can't interact with people properly because they all think I'm a weirdo.
How many close friends do I have? 0
How many friends do I have? 0
How many acquaintances do I have? 0.25
How many family members do I have? 1
It's not even recognized or appreciated by Americans, they just automatically reject me and then must gossip about how I'm a terrible weirdo. I still try, but there's almost no return on effort. I shouldn't even bother because it's futile.
It's why I do most everything for myself, by myself, and I never depend on anyone else unless I pay them (transactionalization and commodification of every interaction).
If you don't plan on having a family, I highly-suggest staying in top physical and mental shape, or you'll end-up warehoused in some disgusting, horrible place at the end of your life where your life will be hell and cut short.
How many times have I thought about suicide? Hundreds. Seriously? Dozens.
