well i would say this is definitely true if you aren’t properly diagnosed and treated as a child as was the case with me and what you described is something i can very much relate to i’ve noticed that my friends who were diagnosed and medicated in elementary or middle school did pretty well were able to go without medication following college in some cases and functioned very normally      i have an iq that’s decently above average something that humble me always cringes to say but those who don’t know me well generally assume the exact opposite where my close friends know how smart i actually am    i was raised in a family where they well my mother in particular believed that my high intelligence meant i was being lazy and needed to apply myself more i was never taken to a single therapist or anything despite the school psychologist and teachers recommending it - there had been a few deaths in the family around the time symptoms became significant and my parents told the school i was just going through something well that wasn’t true and years later i still struggled and couldn’t complete college      the ironic and furious thing is that when growing up my parents were very well off and they spent tons of money on tutors and the like which barely made a dent in my academics yet despite very obvious symptoms never spent money on a therapist or psychiatrist of course things were compounded even more when i developed ptsd from a few traumatic events close together       it seems that the baby boomer generation and older ones just simply don’t get or care very much about psychology and how debilitating psych issues can be
