I never had meds as a kid, only as an adult. I hated them, and I did not feel better. I probably behaved better around others, but I was dead inside and it felt artificial. I knew what was happening and felt awful.
I am not going to diagnose someone online. But keep in mind meds are not for everyone and the change you see vs. What they experience may be vastly different things.
I wish you the best of luck.
