So, I struggled massively with ADHD symptoms in my teens and 20s. Despite failing out of school, and struggling in all the classic ways, I was never diagnosed.
My folks "didn't want the kids on pills" and so despite needing help I was just called lazy and never received any help.
The best way to mitigate the symptoms is with stimulants. I self prescribed caffeine. If I was in a different environment that could have easily been something illegal.
I was never diagnosed and I wish I was, because if I could have focused on classwork in high school, I could have went to college, and I could have started doing work that interests me at the beginning of my 20s instead of the end of my 20s.
You need to examine your shallow attitude about medication. It's "I don't like it because other stuff is better", and a bunch of anxiety around what if what if what if.
What if you deny your child the one tool that actually allows them to reach their potential? You try these "better" options and waste their youth instead of using methods that are proven to be reliable?
