So it's now undeniable that I've had serious and untreated ADHD my whole life. I'm in my mid 30s what would being medicated realistically feel like for me?

Every screening and official diagnostic I've taken has me scoring max ADHD points and every time someone describes a symptom I'm left confused that other people don't have them.

Will my personality change? I feel like being a disorganized disheveled loud interrupter is most of my personality at this point idk.

I've never done any stimulants beyond drinking a million coffees per day so i have some anxiety about this
