It’s quite possible you don’t have ADHD. They diagnosed me with ADHD and gave me Adderall. It threw me in to manic episode which landed me into the hospital.
I was diagnosed with ADHD at age 13 when my parents were at a loss as to why I could not focus on my schoolwork and homework. They gave me Ritalin at the time, which only made me hostile (their words; I don't recall)
