Depression can be a symptom of adhd. At least in women, depression and anxiety are more common than hyperactivity.
Unfortunately, some GPs fixate on 1 or 2 symptoms. That’s where having a checklist is useful. It shows patterns, not just individual symptoms.
Meds definitely change mine. My wife will sometimes notice I’ve forgotten to take my medication before I do.
I like both versions of me, but their usefulness is task dependent.
