It has for me.
After being diagnosed with ADHD in my 40's, and then doing a lot of reading on it, I believe that ADHD is the root cause of much of my families dysfunction. Before I was diagnosed, I tried to figure out what made my family be as crazy as they were, (including me). In my mid 30's, I would talk to some of my Aunts/Uncles, who told me some family stories - that I wouldn't be told to me as a kid. Probably, when I was a kid, you just did't talk about family problems (keep those skeletons hidden! Just pretend it doesn't exist. You can't talk about Grandpa's alcoholism, etc).
The other problem is that the previous generation instills upon their kids, their weird habits and especially in how to NOT properly deal with problems that come up in everybody's life.
And then the next generation does the same thing to their kids. Repeat, and repeat, and......
I've tried talking to several remaining family members about ADHD and it's negative affects on everyone in our family. But they don't believe me, or care? But certainly they don't want to change.
In my family there is alcoholism and other substance abuse, suicide, infidelity. And many who just don't get "IT", whatever IT is, because it's so hard to define. It's feels like I grew up in a circus.
This will be very difficult for some to answer, especially on a public forum, even though we're all disguised as an Avatar, and under a made up name. It will feel like Betrayal. Betrayal because you'll feel as if you'll be talking negatively (hurting, bad-mouthing) your parents, etc. Even though you'll be telling the truth, there's still the over whelming love for them, and the desire to have the relationship you always wanted (and deserved), but never got from your parents. Of course, you can tell how little or how much as you want to share.
Contentment, peace of mind, and most importantly---Relief, to all.
