Hyperactivity typical morphs into anxiety/depression/mood disorder/etc...as an ADHDer tries desperately to control their behaviors. We isolate inside, ruminate constantly, and from there shame and guilt become anxiety and depression...and then you can end out with 3-4 diagnoses and competing media. (NOTE SAYING THIS IS THE CASE FOR EVERYONE, nor am I a doctor)

But I went through about 7 misdiagnosis because I was dxed until my 30s. Without treatment for the first 30 years of my life, I definitely developed anxiety and mood swings. But those were symptoms of the real problem.

Once I got stabilized on dextroamphetamine and began learning the life skills that work for adhders....my anxiety faded, and my anger/shame/frustration(mood swings) did as well.

Just my two cents....
