I had a childhood diagnoses. Parents took me off meds before i was 10 because they didnt like how i was on them (Straterra appetite suppression mostly, i just wouldn't eat). Puberty then hit, and my newfound appetite leads to me discovering i really like food.

Now adult, symptoms never went away. My childhood medical records AFAIK don't even exist anymore (or if they do, its on the dark web. Thanks, DoD/tricare!) and my parents didnt keep anything.
